    cancellation & simplification

    Hello,

    Can someone please help me with the steps to simplify this problem?

    (12(x+4)^2) / (2 sqrt(4(x+4)^3)

    I'm a bit confuse at the process.

    Thanks

    Hi is this the question?

    \frac{12(x+4)^2}{2\sqrt{4(x+4)^3}}

    if so remember that \sqrt{xy}=\sqrt{x}\sqrt{y} and that

    \sqrt[a]{x^b}=x^{\frac{b}{a}}

    Using these two properties we can simplify the denominator to get

    2\sqrt{4(x+4)^3}=2\sqrt{4}\sqrt{(x+4)^3}=2\cdot 2 \cdot (x+4)^{\frac{3}{2}}

    Just keep on simplifying
