Homework Statement
I have problems understanding part (f) of the following worked example:

The Attempt at a Solution
So in part (f), when calculating [tex](\sigma \tau)^{9000}[/tex], how does [tex](\sigma \tau)^{818 \times 11} (\sigma \tau)^2[/tex] reduce to [tex](\sigma \tau)^2[/tex]? What happens to the [tex](\sigma \tau)^{818 \times 11}[/tex] part?
Similarly in [tex](\sigma \tau)^{-21}=(\sigma \tau)^{-2 \times 11} (\sigma \tau)^1 = (\sigma \tau)^1[/tex]
why has the "[tex](\sigma \tau)^{-2 \times 11}[/tex]" been omitted?
