which two square roots are used to estimate 47? I think its the square root of 49 and 36.
correct. Just as 47 is in between 36 and 49, the root is in between 6 and 7.
To estimate the square root of 47, we need to find two perfect square numbers that are close to 47. The perfect squares are numbers that can be expressed as the product of an integer multiplied by itself.
We can make an educated guess and choose the perfect square numbers that are closest to 47. In this case, the perfect square numbers closest to 47 are 49 and 36.
The square root of 49 is 7 because 7 * 7 = 49.
The square root of 36 is 6 because 6 * 6 = 36.
Using these two square roots, we can estimate the square root of 47 would be between 6 and 7.
