Algebra II Recipe: Changing a Logarithmic Equation to an Exponential Equation
Equation
Since logbx = y is equivalent to by = x a logarithmic equation can be expressed as an exponential equation.
A. Given log28 = 3
  1. The base (2) is the b.
  2. The (3) is the y.
  3. The (8) is the x.
  4. Exponential Equation —› 23 = 8
B. Given log10100 = 2
  1. The base (10) is the b.
  2. The (2) is the y.
  3. The (100) is the x.
  4. Exponential Equation —› 102 = 100
C. Given log100.001 = -3
  1. The base (10) is the b.
  2. The (-3) is the y.
  3. The (0.001) is the x.
  4. Exponential Equation —› 10-3 = 0.001
