Which expression is equivalent to (a^-3 b/a^-5 b3)^-3? Assume a≠0, b≠0.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

faster, im not sure why but i know it is faster

i agree because i see the other persons thinking is clear

answer: sorry i dont really know but can we talk all my friends r gone and im bored
