Question

write the expression as a product.
$x^4=(3)^4$
$=?$
$3 \cdot 4$
$3 \cdot 3 \cdot 3 \cdot 3$
$4 \cdot 3$
$4 \cdot 4 \cdot 4$

Explanation:

Step1: Recall exponent definition

An exponent \( a^n \) means multiplying \( a \) by itself \( n \) times. So \( 3^4 \) means 3 multiplied 4 times.

Step2: Expand \( 3^4 \)

Using the exponent rule, \( 3^4 = 3 \cdot 3 \cdot 3 \cdot 3 \).

Answer:

\( 3 \cdot 3 \cdot 3 \cdot 3 \) (corresponding to the option "3·3·3·3")
