    Heres a question that I had in the most recent mock we done and i'm not too sure how to solve it, additionally I cannot just ask my teacher as it's half term. If someone could tell me the answer along with the steps that would be great,


    Question:
    Simplify (2/sqrt(2))^3
    Give your answer in the form a*sqrt(2) where a is an integer.

    I couldn't understand how I would get the fraction into the specified form, I feel as though there is some integral concept that I am not aware of.


    Thanks in advance,

    What is  \sqrt{2} in index form?

    Now, what is  \displaystyle \frac{2}{\sqrt{2}} in index form? Raise this to the power of 3 and can you see what to do from here?
