    Struggling to see how that is the same as 5/4, can you explain please?
    Thanks

    EDIT: Also, why are 1^-1 and 1^-2 still only 1, and not -1? Can you explain that to me?

    Because (1)^-2 is literally just 1. So it's just 5/4 multiplied by 1 which is 5/4.

    Because the power is applied to the one in the brackets. So it's 5/4 lots of one.

    (1)^(-2) = 1/[(1)^2] = 1/1 = 1

    1^-1 is the same as 1/1, and 1^-2 is the same as 1/(1^2).
