Solving for x logarithms
WebSolving logarithmic and exponential equations. To work with logarithmic equations, you need to remember the laws of logarithms: WebSolve each logarithmic equation in Exercises 49–92. Be sure to reject any value of x that is not in the domain of the original logarithmic expressions. Give the exact answer. Then, where necessary, use a calculator to obtain a decimal approximation, correct to two decimal places, for the solution. log2(x+25)=4
