CC.2.2.8.B.1

Apply concepts of radicals and integer exponents to generate equivalent expressions.

M08.B-E.1.1.2

Use square root and cube root symbols to represent solutions to equations of the form x^2 = p and x^3 = p, where p is a positive rational number. Evaluate square roots of perfect squares (up to and including 12^2) and cube roots of perfect cubes (up to and including 53) without a calculator. Example: If x^2 = 25 then x = ±√25.
