Try following PEMDAS, solve the exponent and parenthesis in the denominator then multiply by -4 The question also asked for positive exponents, be careful

UkuleleGirl:

Yes, this is where i made my mistake.

UkuleleGirl:

-5*3 is -15. -15+3 is -12 Idk what else to do

Extrinix:

The way I learned converting negative exponents to positives was this: Whenever a fraction has exponents on both the numerator and denominator, you can swap those exponents and change the negative to a positive. It works the same way as "flipping it" into a fraction of vice versa. (E.g. \(x^{-3}=x^{\dfrac{1}{3}}\) 2nd e.g., \(\dfrac{x^{-2}}{x^{-9}}=\dfrac{x^{9}}{x^{2}}\))

Extrinix:

You can continue from here: (before & after the neg-to-pos exponents rule) \(\dfrac{-5d^{-3}}{-4d^{-15}}=\dfrac{-5d^{15}}{-4d^{3}}\)
