Solving exponential equations with logarithms worksheet

• How do you solve exponential equations with a logarithm?

  We know that, 43 = 64 4 3 = 64 . Rewrite 64 64 as 43 4 3 so each side has the same base. By the property of equality of exponential functions, if the bases are the same, then the exponents must be equal. Add 1 1 to each side. Divide each side by 2 2 . If the bases are not same, then use logarithms to solve the exponential equations.

• How do you rewrite a log as an exponential?

  Section 4.4 Logarithmic Properties 293 Method 1: Rewrite as an exponential. Recall that since the common log is base 10, log( A) =Bcan be rewritten as the exponential 10B=A. Likewise, log( 2x− 6) = 3 can be rewritten in exponential form as 103 = 2x− 6 Method 2: Exponentiate both sides. If A=B, then A =10B.

• How to solve exponential equations with same base?

  Exponential equations are equations in which variables occur as exponents. For example, exponential equations are in the form ax = by a x = b y . To solve exponential equations with same base, use the property of equality of exponential functions . If b b is a positive number other than 1 1 , then bx = by b x = b y if and only if x = y x = y .
