Convert ln(3x) = 5 into exponential form. a) e3x = 5 b) e5 = 3x c) (ln)5 = 3x d) (3x)5 = ln

Step-by-step explanation:

The exponential function and the natural log are inverse functions:

  e^ln(x) = x

Using both sides of your given equation as exponents for e, we have ...

  e^(ln(3x)) = e^5

From the above, we know that ...

  e^(ln(3x)) = 3x

so we can substitute that into the preceding equation to get ...

  3x = e^5

Swapping sides of the equal sign gives an equation that matches choice B:

  e^5 = 3x

they are simplified
