Brilliant Strategies Of Tips About How To Get Rid Of Logarithms

A logarithm says how many of one number to multiply to get another number so a logarithm actually gives us the exponent as its answer:

How to get rid of logarithms. Logarithmic equations are equations with logarithms in them. How many of one number multiply together to make another number? So ln ( x) = log e ( x ).

Logarithms, like exponents, have many helpful properties that can be used to simplify logarithmic expressions and solve logarithmic equations. Product rule the logarithm of the product is the sum of the logarithms of the factors. The equation log x = 100 is another way of writing 10_ x _ = 100.
