# Is it equivalent to raising every term by 4?

Algebra Level 2

We know that $\underbrace{4 \times 4 \times 4 \times 4}_{4 \text{ times}} = 4^4.$

But how many $4^4$ are there in the left side of the equality $\underbrace{4^4 \times 4^4 \times \cdots \times 4^4}_{\text{How many times?}} = {\large 4^{\left( 4^4 \right)}} ?$
