1. Can √72 be completely simplified if it is broken up as √72=√9x8, explain why or why not?

2. How do you determine the result of taking the square root of a variable raised to an even power? For example √x∧28?

Respuesta :

sqrt72 = sqrt(9x8) = 3sqrt8 = 3(sqrt(4x2)) = 3(2sqrt2) = 6 sqrt(2)

2. sqrt x = x^½. Rules of indices states for a power of a power, you times them.
so (x^28)^½ = x^14
