Answer:_______________ |
| 1) What is the positive square root of 4356 Answer: 66 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 4356. Figure out which number squared (multiplied by itself) equals 4356. The number 662 squared equals 4356. 4356 = 66 × 66 = 4356 So the positive √ 4356 is 66. |
| 2) What is √ 121 Answer: 11 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 121. Figure out which number squared (multiplied by itself) equals 121. The number 112 squared equals 121. 121 = 11 × 11 = 121 So √ 121 is 11. |
| 3) 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. |
| 4) What is the positive square root of 3249 Answer: 57 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 3249. Figure out which number squared (multiplied by itself) equals 3249. The number 572 squared equals 3249. 3249 = 57 × 57 = 3249 So the positive √ 3249 is 57. |
| 5) What is √ 529 Answer: 23 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 529. Figure out which number squared (multiplied by itself) equals 529. The number 232 squared equals 529. 529 = 23 × 23 = 529 So √ 529 is 23. |
| 6) What is √ 49 Answer: -7 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 49. Figure out which number squared (multiplied by itself) equals 49. The number -72 squared equals 49. 49 = -7 × -7 = 49 Finally, include the negative sign to get the negative square root. So √ 49 is -7. |
| 7) What is the positive square root of 9216 Answer: 96 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 9216. Figure out which number squared (multiplied by itself) equals 9216. The number 962 squared equals 9216. 9216 = 96 × 96 = 9216 So the positive √ 9216 is 96. |
| 8) What is √ 784 Answer: 28 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 784. Figure out which number squared (multiplied by itself) equals 784. The number 282 squared equals 784. 784 = 28 × 28 = 784 So √ 784 is 28. |
| 9) 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 Finally, include the negative sign to get the negative square root. So √ 729 is -27. |
| 10) What is the positive square root of 4624 Answer: 68 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.
