I am having great difficulty with this any help would be appreciated.
Write this expression in the form e^kx for a suitable constant k.?
(e^4x * e^6x)^3/5, 1/e2^x

which expression, you appear to have two of them
I will do the first one:
(e^4x * e^6x)^3/5
= (e^(10x))^(3/5)
= e^(6x) , so the "suitable" constant k is 6
your second expression is much too ambiguous to attempt.
You will have to use brackets.
is it (1/e)  2^x ? or
1/(e  2^x) ? or
1/(e2)^x ?
