Answer:_______________ |
| 1) What is √ 4 Answer: -2 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 4. Figure out which number squared (multiplied by itself) equals 4. The number -22 squared equals 4. 4 = -2 × -2 = 4 Finally, include the negative sign to get the negative square root. So √ 4 is -2. |
| 2) What is √ 400 Answer: 20 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 400. Figure out which number squared (multiplied by itself) equals 400. The number 202 squared equals 400. 400 = 20 × 20 = 400 So √ 400 is 20. |
| 3) What is the positive square root of 3025 Answer: 55 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 3025. Figure out which number squared (multiplied by itself) equals 3025. The number 552 squared equals 3025. 3025 = 55 × 55 = 3025 So the positive √ 3025 is 55. |
| 4) 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. |
| 5) 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 So √ 324 is 18. |
| 6) What is the positive square root of 2025 Answer: 45 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 2025. Figure out which number squared (multiplied by itself) equals 2025. The number 452 squared equals 2025. 2025 = 45 × 45 = 2025 So the positive √ 2025 is 45. |
| 7) What is √ 256 Answer: -16 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 256. Figure out which number squared (multiplied by itself) equals 256. The number -162 squared equals 256. 256 = -16 × -16 = 256 Finally, include the negative sign to get the negative square root. So √ 256 is -16. |
| 8) What is √ 729 Answer: 27 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 729. Figure out which number squared (multiplied by itself) equals 729. The number 272 squared equals 729. 729 = 27 × 27 = 729 So √ 729 is 27. |
| 9) What is the positive square root of 9025 Answer: 95 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 9025. Figure out which number squared (multiplied by itself) equals 9025. The number 952 squared equals 9025. 9025 = 95 × 95 = 9025 So the positive √ 9025 is 95. |
| 10) What is √ 64 Answer: -8 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 64. Figure out which number squared (multiplied by itself) equals 64. The number -82 squared equals 64. 64 = -8 × -8 = 64 Finally, include the negative sign to get the negative square root. So √ 64 is -8. |
