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

depends. See explanation

Explanation:

I assume you meant "write $4 x \cdot 4 x \cdot 4 x$ in exponential form"
Here's a tip: every $4 x$ can be written as ${\left(4 x\right)}^{1}$. So:
${\left(4 x\right)}^{1} \cdot {\left(4 x\right)}^{1} \cdot {\left(4 x\right)}^{1}$

When multiplying exponentials with the same base, you add the exponents. So this means
${\left(4 x\right)}^{1 + 1 + 1} = {\left(4 x\right)}^{3}$

Need a simpler format?
${\left(4 x\right)}^{3} = {4}^{3} {x}^{3} = 64 {x}^{3}$
