n=-3
D. Incorrect
-1-22n=-20n-9
8=2n
n=4
U get a calculator and u put 4^2+7^4 n u put it in the calculator but the pic shows what a sqaure root looks like n u see the button with the x2 u can press that for when u put the 4 square root 2 then plus 7 n then u hit the button that has this symbol ^ n hit 4 then equal an itll give u the answer which is 2417.
