Question

How do you write "4x (times) 4x (times) 4x" in exponential form?

Answer 1

depends. See explanation

Explanation:

I assume you meant "write `4x*4x*4x` in exponential form"
Here's a tip: every `4x` can be written as `(4x)^1`. So:
`(4x)^1*(4x)^1*(4x)^1`

When multiplying exponentials with the same base, you add the exponents. So this means
`(4x)^(1+1+1)=(4x)^3`

Need a simpler format?
`(4x)^3=4^3x^3=64x^3`
