Answer:_______________ |
| 1) What is the positive square root of 1600 Answer: 40 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 1600. Figure out which number squared (multiplied by itself) equals 1600. The number 402 squared equals 1600. 1600 = 40 × 40 = 1600 So the positive √ 1600 is 40. |
| 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 Finally, include the negative sign to get the negative square root. So √ 121 is -11. |
| 3) 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. |
| 4) 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. |
| 5) 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. |
| 6) 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 So √ 324 is 18. |
| 7) What is the positive square root of 7396 Answer: 86 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 7396. Figure out which number squared (multiplied by itself) equals 7396. The number 862 squared equals 7396. 7396 = 86 × 86 = 7396 So the positive √ 7396 is 86. |
| 8) 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 Finally, include the negative sign to get the negative square root. So √ 484 is -22. |
| 9) What is √ 4 Answer: 2 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 4. Figure out which number squared (multiplied by itself) equals 4. The number 22 squared equals 4. 4 = 2 × 2 = 4 So √ 4 is 2. |
| 10) What is the positive square root of 2209 Answer: 47 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 2209. Figure out which number squared (multiplied by itself) equals 2209. The number 472 squared equals 2209. 2209 = 47 × 47 = 2209 So the positive √ 2209 is 47. |
