Question

Consider this equation..

Answer 1

45

Explanation:

`\sqrt{x^(4) } -y^(2)`

Plug in 3 for x and -6 for y

`=√(3^4)-\left(-6^2\right)`

`=√(3^4)+6^2`

`=\sqrt{3^(4) } =3^(2)`

`=3^2+6^2`

`3^(2) =9`

`=9+6^2`

`6^(2) =36`

`=9+36`

`=45`

Answer 2

-27

Explanation:

`√(x^4) - y^2\\√(3^4) - (-6)^2\\√(3*3*3*3) - 36\\3*3 - 36\\9 - 36\\-27`
