Question

Simplify the

expression below.

-5x-³y²
—————
Z-⁴

Couldn’t get negative powers sorry

Answer 1

`\mbox{\large {-(5y^2z^4)/(x^3)}}`

Explanation:

We have the following expression and asked to simplify

`(\left(-5x^(-3)y^2\right))/(z^(-4))`

Using the exponent rule: x⁻a = 1/xᵃ we get x⁻³ = 1/x³

Using the exponent rule 1/x⁻ᵃ = xᵃ we get 1/z⁻⁴ = z⁴

The resultant expression becomes:

`-(5y^2z^4)/(x^3)`

This cannot be simplified any further since the variables are different
