Answer:_______________ |
| 1) What is √ 841 Answer: -29 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 841. Figure out which number squared (multiplied by itself) equals 841. The number -292 squared equals 841. 841 = -29 × -29 = 841 Finally, include the negative sign to get the negative square root. So √ 841 is -29. |
| 2) What is the positive square root of 7225 Answer: 85 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 *3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 7225. Figure out which number squared (multiplied by itself) equals 7225. The number 852 squared equals 7225. 7225 = 85 × 85 = 7225 So the positive √ 7225 is 85. |
| 3) What is √ 25 Answer: 5 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 25. Figure out which number squared (multiplied by itself) equals 25. The number 52 squared equals 25. 25 = 5 × 5 = 25 So √ 25 is 5. |
| 4) What is √ 900 Answer: -30 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 900. Figure out which number squared (multiplied by itself) equals 900. The number -302 squared equals 900. 900 = -30 × -30 = 900 Finally, include the negative sign to get the negative square root. So √ 900 is -30. |
| 5) What is the positive square root of 5776 Answer: 76 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 *3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 5776. Figure out which number squared (multiplied by itself) equals 5776. The number 762 squared equals 5776. 5776 = 76 × 76 = 5776 So the positive √ 5776 is 76. |
| 6) What is √ 36 Answer: 6 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 36. Figure out which number squared (multiplied by itself) equals 36. The number 62 squared equals 36. 36 = 6 × 6 = 36 So √ 36 is 6. |
| 7) What is √ 324 Answer: -18 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 324. Figure out which number squared (multiplied by itself) equals 324. The number -182 squared equals 324. 324 = -18 × -18 = 324 Finally, include the negative sign to get the negative square root. So √ 324 is -18. |
| 8) What is the positive square root of 4761 Answer: 69 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 *3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 4761. Figure out which number squared (multiplied by itself) equals 4761. The number 692 squared equals 4761. 4761 = 69 × 69 = 4761 So the positive √ 4761 is 69. |
| 9) What is √ 100 Answer: 10 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 100. Figure out which number squared (multiplied by itself) equals 100. The number 102 squared equals 100. 100 = 10 × 10 = 100 So √ 100 is 10. |
| 10) What is √ 225 Answer: -15 SOLUTION 1 : Remember: To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number. Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root. For example, 9 = 3 since 9 = 32 and 3 is positive. Solve: You want to find the positive square root of 225. Figure out which number squared (multiplied by itself) equals 225. The number -152 squared equals 225. 225 = -15 × -15 = 225 Finally, include the negative sign to get the negative square root. So √ 225 is -15. |
