    Basic Integration Question

    Hi all,

    I've been learning the basics of integration recently, and as I was working through some exercises, I came across a question as seen on the attachment.

    Basic Integration Question-calculus-integration.bmp

    Now, I understand everything up to the part where the square root of "x" is multiplied by 2. In other words, I do not understand how (x to the power of 1/2) divided by 1/2 becomes 2 x square root(x) (a surd). I had another question where (x to the power of 3/2) divided by 3/2 simply became: 3/2 multiplied by (x to the power of 3/2). In the case of the question above, I thought the same principles applied since I am dealing with fractions.

    Any help to clarify will be much appreciated!

    Thanks,

    Nathaniel

    x^{\frac{1}{2}}=\sqrt{x}

    Do you agree with that?

    \frac{1}{\frac{1}{2}}=2

    Do you agree with that?

    If so, then it's easy to see that \frac {x^{\frac{1}{2}}}{\frac{1}{2}}=2\sqrt{x}
