Solving Polynomials

Question

Simplify each expression. Final answers should be written in standard form.

(-4m²n)⁴·1/6m^-10n^-4

I'm confused on how to work this out step-by-step. The exponents should all be positive, following the negative exponent rule, but I'm just unsure how to apply it and work the problem out.

Answer 1

(-4m²n⁴)⁴(1/6m^-10n^-4)

(256m⁸n¹⁶)(m¹⁰n⁴/6)

(256/6)(m¹⁸n²⁰)
