    I've been stuck on this question for ages and have tried loads of different methods but I just can't figure it out.

    Simplify this expression:

    (4a^2 b^1/6)^3 * (3b)^2 all divided by 8a^4*b^3

    please could someone talk me through the steps?

    Expand out all the brackets. For example, (3b)^2 = 9b^2. Do the same for the other set of brackets.

    Now just cancel out common factors of a, b and numbers. For example, if you had 6ab^2 / 4ab (not the actual expression), you could cancel out 2ab from both top and bottom to get 3b/2.
