Answer:
A. 6a/b^7
Step-by-step explanation:
you have to factorize it
simplify the denominator
you know that a^0 = 1
so it becomes: (b^2)^4 ( 1b is the same as b )
using laws of exponents: (a^n)^m = a^m x n
so here: b^2 x 4
which is b^8
now put that in the original question as denominator
6ab/b^8
you can cancel b and b^8
which gives you 6a/b^7
so the answer is A. 6a/b^7
