Question

How do you simplify `5m^-3n^4` and write it using only positive exponents?

Answer 1

See a solution process below:

Explanation:

Use this rule for exponents to eliminate the negative exponent:

`x^color(red)(a) = 1/x^color(red)(-a)`

`5m^color(red)(-3)n^4 = (5n^4)/m^color(red)(- -3) = (5n^4)/m^3`
