Question

In exponent there is logarithms. What is this explain briefly please?????

Answer 1

It can't be said too often: a logarithm is nothing more than an exponent. You can write the above definition compactly, and show the log as an exponent, by substituting the second equation into the first to eliminate y: Read that as “the logarithm of x in base b is the exponent you put on b to get x as a result.
