   ocr: Solve: 32x - 5 we begin by taking the logarithm of each side of the equation log32x =log5 Next we apply the third property of logarithms to write the exponent as a coerricient 2x log3=log5 Dividing each side by 2 log3 isolates x log5 i This is the exact solution 2log3 ( 0.732 Approximate solution We check our solution by substituting 0.732 into our original equation: 32(0.732)25 4.995:5 which is what we expect when we Check an approximate solution Solving Exponential Equations
