Answer:_______________ |
| 1) 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. |
| 2) 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. |
| 3) What is √ 196 Answer: -14 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 196. Figure out which number squared (multiplied by itself) equals 196. The number -142 squared equals 196. 196 = -14 × -14 = 196 Finally, include the negative sign to get the negative square root. So √ 196 is -14. |
| 4) 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. |
| 5) What is the positive square root of 5184 Answer: 72 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 5184. Figure out which number squared (multiplied by itself) equals 5184. The number 722 squared equals 5184. 5184 = 72 × 72 = 5184 So the positive √ 5184 is 72. |
| 6) 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. |
| 7) 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. |
| 8) What is the positive square root of 9604 Answer: 98 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 9604. Figure out which number squared (multiplied by itself) equals 9604. The number 982 squared equals 9604. 9604 = 98 × 98 = 9604 So the positive √ 9604 is 98. |
| 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 √ 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. |
