$\displaystyle\bf\\b)~~~-1,2^2=-(1,2)^2=\boxed{\bf-2,44}~~~\\\\\\f)~~~\left(-1\frac{1}{3}\right)^3=\left(-\frac{1\times3+1}{3}\right)^3=-\frac{4^3}{3^3}=-\frac{64}{27}=\boxed{\bf-2\frac{10}{24}}\\\\\\j)~~~\left(-\frac{200}{199}\right)^0=1\\\\\\n)~~~\left(\frac{1}{3}\right)^4=\frac{1^4}{3^4}=\boxed{\bf\frac{1}{81}}$
