You can find the square root of an irrational number by approximating irrational square roots of them, after you use the calculator. (The calculator gives an approximate root also) For example,

1. Approximate the square root of 4.3 to the nearest hundredth.

Use the calculator, which shows 2. 0736444135.

Since 3 < 5 round down to 2.07 and drop the digits to the right of 7.

2. Approximate the negative square root of 10.8 to the nearest hundredth.

Use the calculator, which shows -3.286335345

Since 6 > 5 round up to -3.29 and drop the digits to the right of 8.
