If you are dealing with logarithms, we can rewrite `log_7 49=2` in exponential form as `7^2=49` .
Logarithms and exponentials are inverses of each other. Depending on the problem type, we can rewrite in the other form as sometimes it is easier to solve.
``For example to solve `log_3 x =4` we can rewrite as `3^4=x` to read off the answer. We have written an equation given in logarithmic form in exponential form.
For complex numbers, the exponential form is a way to express the number using a power of e (e=2.71828, also known as Euler constant).
For complex number z=a+bi, the exponential form is:
