Solve by taking the logarithm of each side

WebNov 15, 2024 · A logarithm is just an exponent. To be specific, the logarithm of a number x to a base b is just the exponent you put onto b to make the result equal x. For instance, since 5² = 25, we know that 2 (the power) is the logarithm of 25 to base 5. Symbolically, log 5 (25) = 2. More generically, if x = by, then we say that y is “the logarithm of x ...
