[tex]1.\ \ 5^{-2}=(\frac15)^2=\frac1{5^2}\\\\ 2.\ \ -7^{-1}=-(\frac17)^1=-\frac1{7^1}\\\\ 3.\ \ t^{-6}=(\frac1t)^6=\frac1{t^6}\\\\ 4.\ \ n^{-2}=(\frac1n)^2=\frac1{n^2}\\\\\\ 5.\ \ (\frac13)^4=3^{-4}\\\\ 6.\ \ (\frac19)^2 =(\frac1{3^2})^2 =(3^{-2})^2=3^{-4}\\\\ 7.\ \ \frac1{49}=\frac1{7^2}=7^{-2}\\\\ 8.\ \ \frac1{8}=\frac1{2^3}=2^{-3} [/tex]
