Explanation:

Step1: Recall exponent rule

The exponent of a number says how many times to use the number in a multiplication. For $b^4$, by the definition of exponents, $b^4=b\times b\times b\times b$.

Step2: Multiply by $a$

Since the original expression is $ab^4$, we multiply $a$ by the expanded - form of $b^4$. So $ab^4=a\times b\times b\times b\times b$.

Answer:

$a*b*b*b*b$
