# Math Help - Exponentials - Quick Question

1. ## Exponentials - Quick Question

Simplify:

$exp(x^3 )^3 = exp(3x^3 )$

2. No, not quite right.

If you put some values in for x then you'll see that's it not right.

The rule you need is:

$(x^n)^m=x^{nm}$

Hope that helps!

3. Turns out the answer was infact:

$
exp(3x^3 )
$

that was the answer you would have found if you followed the hint and that you found =)

$\exp(x^3)^3=\left(e^{x^3} \right)^3=e^{3x^3}=\exp(3x^3)$
