Simplifying Rational Exponents

Question

Simplify. Your answer should contain only positive exponents with no fractional exponents in the denominator.

I don't understand the question

I) 2m^2 x 4^3/2 x 4^-2

I had gotten

.96m^4

is this correct?

Answer 1

(2m²)(4^3/2)(4^-2)

(2m²)(2²)^3/2(2²)^-2

(2m²)(2³)(2^-4) Laws of Exponents

(2¹)(2³)(2^-4)(m²)

Can you simplify and answer?
