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

Is the answer right? Thanks.

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:

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

Hope that helps! - Oct 23rd 2008, 12:04 PMr_maths
Turns out the answer was infact:

$\displaystyle

exp(3x^3 )
