Find all the second order partial derivatives of the given function.f(x, y) = (x2 + y2)7
A. fxx(x, y) = 168x2(x2 + y2)5 + 14(x2 + y2)6; fyy(x, y) = 168y2(x2 + y2)5 + 14(x2 + y2)6; fxy(x, y) = fyx(x, y) = 168xy(x2 + y2)6 + (x2 + y2)7 B. fxx(x, y) = 168x2(x2 + y2)5 + 14(x2 + y2)6; fyy(x, y) = 168y2(x2 + y2)5 + 14(x2 + y2)6; fxy(x, y) = fyx(x, y) = 168xy(x2 + y2)5 + (x2 + y2)6 C. fxx(x, y) = 168x2(x2 + y2)5 + 14(x2 + y2)6; fyy(x, y) = 168y2(x2 + y2)5 + 14(x2 + y2)6; fxy(x, y) = fyx(x, y) = 168xy(x2 + y2)5 + 14(x2 + y2)6 D. fxx(x, y) = 168x2(x2 + y2)5 + 14(x2 + y2)6; fyy(x, y) = 168y2(x2 + y2)5 + 14(x2 + y2)6; fxy(x, y) = fyx(x, y) = 168xy(x2 + y2)5 + 14xy(x2 + y2)6
