= -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}
