    does it say what x and y stand for

    you can look at the equation in a simpler form to start with: \[\sqrt{a \times b} = \sqrt{a} \times \sqrt{b}\] so your equation can be written as \[\sqrt{x ^{36}} \times \sqrt{y ^{64}}\]

    I assume you are studying indices do you know how to write squareroot as an index?

    \[\sqrt{x} = x ^{\frac{ 1 }{ 2}}\] do you recognise that?

    ok so look at my post above you have 2 sqareroots - but you can write them like I did above with an index like this: \[(x ^{36})^{\frac{ 1 }{ 2 }} \times (y ^{64})^{\frac{ 1 }{ 2}}\] NOw you need to use what you know about indices to simplify that....

    \[(x ^{a})^{b} =x ^{a \times b}\] use that on the 2 terms above (This is the last stage - you need to do it yourself)
