$y^{3} = 27$ $y^3=27$

You did not request that the value for y be determined. Only how the notation be represented.

Use the definition of log:

Explanation:

You take the base $y$ $y$ and "push" up the $3$ $3$ getting rid of the log to get:
$27 = y^{3}$ $27=y^3$
where you can see that $y = 3$ $y=3$ because $3^{3} = 27$ $3^3=27$ .
