A new lesson is available on the Basic Math page that involves taking the square root of a positive integer, or raising an integer to a power >= 0. For square roots that are non-integer answers, the calculator will drive the math to show you how to express the answer as a product of an integer and a radical. Else, it will show you the guess and check method or the long way where you list out each square result for integer square roots.
For raising a number to a power calculation, the calculator will list out the math behind the powers. This lesson is searchable by exponent, power, radical, square root, located here --> Square Roots and Powers of Numbers
