    Stuck on this question:

    Given that

    Show that y=8x^2
    Note that 3 = 3\times 1 = 3 \log_22

    Can you take it from there?

    I posted it on the other one but here:

    3+log2(x^2)=log2(y)
    log2(x^2)-log2(y)=-3
    log2(x^2/y)=-3
    x^2/y=2^-3
    x^2/y=1/8

    And then solve for y
