Use the properties of logarithmic functions to simplify the expression on the left side of the equation and determine the values of x and y. Then evaluate the simplified expression. The value of x is , and the value of y is. The value of the expression, rounded to nearest hundredth, is .
4x = 16log 4x = log 16Take the common logarithm of both sides. (Remember, when no base is written, that means the base is 10.) What can you do with that new equation?log 4x = log 16x log 4 = log 16Use the power property of logarithms to simplify the logarithm on the left side of the equation.x log 4 = log 16Remember that log 4 is a number. You can divide both sides of the equation by log 4 to get x by itself.AnswerUse a calculator to evaluate the logarithms and the quotient.
