WebA logarithm of a number with a base is equal to another number. A logarithm is just the opposite function of exponentiation. For example, if 102 = 100 then log10 100 = 2. Hence, we can conclude that, Logb x = n or bn = x. Where b is the base of the logarithmic function. This can be read as “Logarithm of x to the base b is equal to n”. WebSolve the logarithmic equabon.
