Question

How do you simplify `2x^-4y^2` and write it using only positive exponents?

Answer 1

See the entire explanation below:

Explanation:

Use this rule for exponents to eliminate the negative exponent:

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

`2x^color(red)(-4)y^2 = (2y^2)/x^color(red)(- -4) = (2y^2)/x^4`
