Answer:_______________ |
| 1) What is the positive square root of 8100 Answer: 90 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 8100. Figure out which number squared (multiplied by itself) equals 8100. The number 902 squared equals 8100. 8100 = 90 × 90 = 8100 So the positive √ 8100 is 90. |
| 2) 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 So √ 256 is 16. |
| 3) 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. |
| 4) What is the positive square root of 7056 Answer: 84 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 7056. Figure out which number squared (multiplied by itself) equals 7056. The number 842 squared equals 7056. 7056 = 84 × 84 = 7056 So the positive √ 7056 is 84. |
| 5) 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 So √ 49 is 7. |
| 6) What is √ 9 Answer: -3 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 9. Figure out which number squared (multiplied by itself) equals 9. The number -32 squared equals 9. 9 = -3 × -3 = 9 Finally, include the negative sign to get the negative square root. So √ 9 is -3. |
| 7) What is the positive square root of 5625 Answer: 75 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 5625. Figure out which number squared (multiplied by itself) equals 5625. The number 752 squared equals 5625. 5625 = 75 × 75 = 5625 So the positive √ 5625 is 75. |
| 8) What is √ 16 Answer: 4 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 16. Figure out which number squared (multiplied by itself) equals 16. The number 42 squared equals 16. 16 = 4 × 4 = 16 So √ 16 is 4. |
| 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 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. |
