LOGS EQUAL THE

The inverse of an exponential function is a logarithmic function. Logarithmic Function x = log a y read: “x equals log base a of y”

We can convert exponential equations to logarithmic equations and vice versa, using this:

Convert to exponential form 1) 2) 3)

Convert to logarithmic form 4) 5) 6)

Now that we can convert between the two forms we can simplify logarithmic expressions. Without a Calculator!

Simplify 1) log 2 32=x 2) log 3 27=x 3) log 4 2=x 4) log 3 1=x 2 x = 32 3 x = 27 4 x = 2 3 x = 1 x = 5 x = 3 x = 1/2 x = 0 “What is the exponent of that gives you 32?” “What is the exponent of 3 that gives you 27?”

Evaluate
