The expression equivalent to given expression is $\frac{b^4}{a}$

<em><u>Solution:</u></em>

Given expression is:

$\frac{a^3b^5}{a^4b}$

We are asked to find the expression equivalent to given expression

Assume that denominator does not equal to zero

We can apply the exponent rule in given expression

$\frac{x^a}{x^b} = x^{a - b}$

Apply the above rule in given expression

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

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

Thus the equivalent expression is found
