Find the minimum of the Brown's badly scaled function using Powell's method,mathematically. f$($x$)=($x$\_(1)-10^(6))^(2)+($x$\_(2)-2*$ Q$3)$ Find the minimum of the Brown's badly scaled function using Powell's method.

$f(x)=(x_1-{10}^6{)}^2+(x_2-2{10}^{-6}{)}^2+(x_1{x}_2-2{)}^{2}10^(-6))^(2)+($x$\_(1)$x$\_(2)-2)^(2)$
