Answer 1

Answer:

$\frac{b^{4} }{a}$

Step-by-step explanation:

$\frac{a^{3}b^{5} }{a^{4}b }$ is the equation we need to simplify. In order to do this, we must remember what these exponents mean.

$\frac{a^{3}b^{5} }{a^{4}b }$ = $\frac{aaabbbbb}{aaaab}$

Now, we see that we can divide and cancel.

$\frac{aaabbbbb}{aaaab}$ = $\frac{bbbb}{a}$ = $\frac{b^{4} }{a}$

Another way we can solve this is by knowing that exponents in the denominator become negative when we move them to the numerator:

$\frac{a^{3}b^{5} }{a^{4}b }$ = $a^{3}b^{5}a^{-4}b^{-1}$ = $a^{-1}b^{4}$ = $\frac{b^4}{a}$
