    Any number to the power of 0 is equal to 1 e.g. 8^0 = 1.

    Any number to the power of -1 is the reciprocal of that number e.g. 8^{-1} = \frac{1}{8}

    anything to a power of 0 equals 1 because you can write a^n \times a^{-n}=a^{n-n}=a^0. Also a^n \times a^{-n}=a^n \times  \frac{1}{a^n}=\frac{a^n}{a^n}=1

    It is \div: \div - make sure to use the \ and not /.

    Any number to the power of 0 is always 1:  a^0 = 1

    Negative powers give reciprocals, such that  a ^{-n} = 1/(a^n)

    Whilst not necessarily in the question, fractional powers give roots, such that  a^{(1/n)} = \sqrt[n] {a}

    Using these two rules, try and work out the question now given

    I swear that this did not work earlier ;-)
