To do the divisions, we divide all the same terms together.12 : 15 = 4/5a^4 : a^-2 = a^4 - (-2) = a^6b^-3 : b = b^-3 - (1) = b^-4And do the last step of moving the terms with negative exponents, we get the result shown in the picture.
We have to simplify the expression:
We have the variables a and b with different exponents, that we can simplify applyinf the rules of the exponents.
For example, we can do this:
Answer: (4/5)*a^6/b^4
