Logarithmic Functions Review

Use multiple log properties to write as a single log:
3log₂x -  log₂y

• log₂(x³/y)

• log₂(x³y)

• log₂(x/y)³

• log₂(3x/y)

Use multiple log properties to write as a sum or difference of three logs:  log(2x/7)

• log 2 + log x - log 7

• log 2 - log x + log 7

• log 2 - log x - log 7

• log 2 + log x + log 7

Which is the inverse function of
y = ln x ?

• y = 2^x

• y = e^x

• y = 10^x

• y = 4^x
