Question

How do you simplify `(-2x^-5) x^7`?

Answer 1

`= -2x^2`

Explanation:

the above `(-2x^(-5))x^7` can be written like this :

`=-2*x^(-5)*x^7`]

{so here we have two identical variables and they are being multiplied so we will add there exponents like this}

`= 2*x^(-5+7)`

`= -2*x^2`

`= -2x^2`

{remember when same variables with different exponents are multiplies there exponents are added and when they are divided there exponents are subtracted}
