Question

use multiplication to fully expand the expression below. (ab)^4 answer attempt 1 out of 2 press the · button or type the * symbol on your keyboard to represent multiplication. using × for multiplication is inappropriate when x may be used as a variable. expanded form:

Explanation:

Step1: Recall exponent rule

By the rule $(xy)^n=x^n\times y^n$, for $(ab)^4$, we have $(ab)^4 = a^4\times b^4$. And by the definition of exponents, $a^4=a\times a\times a\times a$ and $b^4=b\times b\times b\times b$.

Step2: Write expanded form

$(ab)^4=a\times a\times a\times a\times b\times b\times b\times b$

Answer:

$a\times a\times a\times a\times b\times b\times b\times b$
