# X 2 log x 2 1

log5(-1) are both undefined and therefore x -3 is not a solution. Log4(x 1) log4(x 1)1/2 log4(8) We use the product rule to write. Logarithm as inverse function of exponential function. Logarithmic equations are equations involving logarithms. Example 2: Solve the logarithmic equation log5(x - 2) log5(x 2). Log b ( x / y ) log b ( x ) - log b ( y ) For example: log10(3 / 7) log10(3) - log10(7) Logarithm power rule The logarithm of x raised to the power of y is y times the logarithm.
