Answer:

[tex]y=e^{3}*x^{2}[/tex]

Step-by-step explanation:

First, use reduction of power property:

[tex]log(x^{y} )=ylog(x)[/tex]

So:

[tex]log(y)=3+log(x^{2} )[/tex]

Cancel logarithms by taking exp of both sides:

[tex]e^{log(y)} =e^{3+logx^{2} }[/tex]

Keep in mind this:

[tex]x^{y} *x^{z} =x^{y+z}[/tex]

Hence:

[tex]y=e^{3} *e^{log(x^{2} )} =e^{3} *x^{2}[/tex]
