Does anyone have any tips on square root exponents without using a calculator. this is worth 20 points answer appropriatly

On square roots, always look at the units digit. Observe the pattern

1^2 ends in 1.

2^2 ends in 4.

3^2 ends in 9.

4^2 ends in 6.

5^2 ends in 5.

6^2 ends in 6.

7^2 ends in 9.

8^2 ends in 4.

9^2 ends in 1.

0^2 ends in 1.

Also, when you have (x5)^2, where x5 is a two digit number in the form of 10x+5, find (x)(x+1), then add 25 at the end.

For example, 25^2. In this case, x is 2. So, 2*3=6. Then add the 25 at the end to get 625.

Square roots are vice versa.
