Answer:

45

Step-by-step explanation:

[tex]\sqrt{x^{4} } -y^{2}[/tex]

Plug in 3 for x and -6 for y

[tex]=\sqrt{3^4}-\left(-6^2\right)[/tex]

[tex]=\sqrt{3^4}+6^2[/tex]

[tex]=\sqrt{3^{4} } =3^{2}[/tex]

[tex]=3^2+6^2[/tex]

[tex]3^{2} =9[/tex]

[tex]=9+6^2[/tex]

[tex]6^{2} =36[/tex]

[tex]=9+36[/tex]

[tex]=45[/tex]
