| 1) What is √ 625 Answer: 25 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 625. Figure out which number squared (multiplied by itself) equals 625. The number 252 squared equals 625. 625 = 25 × 25 = 625 So √ 625 is 25. |
| 2) What is the positive square root of 9801 Answer: 99 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 9801. Figure out which number squared (multiplied by itself) equals 9801. The number 992 squared equals 9801. 9801 = 99 × 99 = 9801 So the positive √ 9801 is 99. |
| 3) What is √ 576 Answer: -24 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 576. Figure out which number squared (multiplied by itself) equals 576. The number -242 squared equals 576. 576 = -24 × -24 = 576 Finally, include the negative sign to get the negative square root. So √ 576 is -24. |
| 4) What is √ 144 Answer: 12 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 144. Figure out which number squared (multiplied by itself) equals 144. The number 122 squared equals 144. 144 = 12 × 12 = 144 So √ 144 is 12. |
| 5) What is the positive square root of 8649 Answer: 93 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 8649. Figure out which number squared (multiplied by itself) equals 8649. The number 932 squared equals 8649. 8649 = 93 × 93 = 8649 So the positive √ 8649 is 93. |
| 6) 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. |
| 7) 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 So √ 900 is 30. |
| 8) What is the positive square root of 6724 Answer: 82 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 6724. Figure out which number squared (multiplied by itself) equals 6724. The number 822 squared equals 6724. 6724 = 82 × 82 = 6724 So the positive √ 6724 is 82. |
| 9) 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. |
| 10) What is √ 484 Answer: 22 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 484. Figure out which number squared (multiplied by itself) equals 484. The number 222 squared equals 484. 484 = 22 × 22 = 484 So √ 484 is 22. |
