Jorge is trying to learn all of the perfect squares. This knowledge will help him estimate square roots that are not perfect. Between which two whole numbers is the square root of 76?
Answer : 7 and 9
What about 8?
I thought it was asking which 2 numbers is the square root of 76 between. The square root of 76 is 8.71779788708
Right. So the square root is between 8 and 9.
8 * 8 = 64
9 * 9 = 81
Thank you
You're welcome, M.
To find between which two whole numbers the square root of 76 lies, you can start by finding the perfect squares that surround 76.
First, find the perfect square that is smaller than 76. The perfect square closest to 76 is 64, because 8^2 = 64.
Next, find the perfect square that is larger than 76. The perfect square closest to 76 is 81, because 9^2 = 81.
Since 76 is between 64 and 81, the square root of 76 must be between 8 and 9. Therefore, the square root of 76 is between integers 8 and 9.
