cubes root of 16x^2

Question

write in exponential form and simplify

Answer 1

(16x²)^1/3 = (2⁴x²)^1/3 = 2^4/3x^2/3 = 2 * 2^1/3x^2/3 = 2(2x²)^1/3 (If you are writing the answer by hand, you would write (2x²)^1/3 using the radical sign with a 3 with 2x² inside)

Answer 2

(16^1/3)x^2/3

=slightly less than 2.52x^2/3
