    simplify by factoring. Assume that all expressions under radicals represent nonegative numbers.

    sqrt50a^2b
    =sqrt25*2*a^28*b
    =sqrt25*sqrt2*sqrta^2*sqrtb
    =5a^2bsqrt2

    It would be easier to help you if you could put this into LaTex markup.

    For example, to get a square root:
     \sqrt{50}
    [tex] \sqrt{50} [tex]

    I really don't know if the a^2b is under the square root sign or not. By the way, you should write a^{2b} as [tex]a^{2b} [/tex]

    \sqrt{50a^2b}=\sqrt{25*2*a^2*b}=\sqrt{25}*\sqrt{2}  *\sqrt{a^2}*\sqrt{b}=5a\sqrt{2b}

    ..

    Almost. You had some digits out of place there. I think I've cleaned it up for you now.
