Example by Mrs. G Logarithmic Equations • If x > 0 and 0 < b ≠ 1, then y = logb(x) iffby = x What does this mean? It means the logarithmic and the exponential are inverses of each other. y y x b x b = x y log = Click to continue. Objective Video Example by Mrs. G Give It a Try
Example by Mrs. G Rewriting Logarithmic to Exponential Read “log base 4 of 64 is 3” Identify base (b): 4 Identify exponent (y): 3 Rewrite as exponential: Is that true? Yes, therefore exponential form should be correct. Click to continue. Objective Video Example by Mrs. G Give It a Try
