Answer 1

Answer:

logx27=3

or

log27x=3

Step-by-step explanation:

Answer 2

Answer:

  $\log_3{27}=x$

Step-by-step explanation:

Starting with ...

  $3^x=27$

and taking the log of both sides, you get ...

$x\cdot\log{3}=\log{27}\\\\x=\dfrac{\log{27}}{\log{3}} \qquad\text{divide by the coefficient of x}\\\\x=\log_3{27} \qquad\text{use the change of base formula}$

This last formulation matches the last answer choice.
