Hi Keith;
ex=4
I believe this question is asking of you to take the Natural Logarithm, In, of each side. A Natural Logarithm is always to the base of e...
In ex=In 4
x In e=In 4
Inee=1 because e=e1
(x)(1)=In 4
x=In 4
x≈ 1.38

Keith, the EXACT answer is x = ln 4. If you use your calculator its results are ALWAYS approximate, no matter how many significant digits you use. Vivian chose to report 3 sig figs, x≈ 1.38, while your 1.3863 is 5 sig figs; but both are still
approximations.
