Question

Question 2 ab5 a7b2 is equivalent to: a a1017 10 a21 a4 a 63

Answer 1

`(b^3)/(a^4)`

Explanation:

We have the following expression:

`(a^3b^5)/(a^7b^2)`

When it is a quotient, and it is the same base, the exponents are subtracted, therefore

`(a^3b^5)/(a^7b^2)=a^(3-7)b^(5-2)=a^(-4)b^3=(b^3)/(a^4)`
