Question

write an expression that is equivalent to $3^4$.

Explanation:

Step1: Recall exponent definition

$3^4$ means multiplying 3 by itself 4 times.

Step2: Write the equivalent expression

So, $3^4 = 3\times3\times3\times3$.

Answer:

$3\times3\times3\times3$ (Other equivalent expressions like $81$ or using exponent rules like $3^2\times3^2$ are also valid, but this is a direct expansion.)
