Answer:_______________ |
| 1) 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. |
| 2) 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 Finally, include the negative sign to get the negative square root. So √ 529 is -23. |
| 3) 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. |
| 4) What is the positive square root of 4225 Answer: 65 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 4225. Figure out which number squared (multiplied by itself) equals 4225. The number 652 squared equals 4225. 4225 = 65 × 65 = 4225 So the positive √ 4225 is 65. |
| 5) 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. |
| 6) 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 So √ 576 is 24. |
| 7) What is the positive square root of 5476 Answer: 74 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 5476. Figure out which number squared (multiplied by itself) equals 5476. The number 742 squared equals 5476. 5476 = 74 × 74 = 5476 So the positive √ 5476 is 74. |
| 8) What is √ 289 Answer: -17 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 289. Figure out which number squared (multiplied by itself) equals 289. The number -172 squared equals 289. 289 = -17 × -17 = 289 Finally, include the negative sign to get the negative square root. So √ 289 is -17. |
| 9) 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. |
