Help needed to solve square root equation

  1. Sep 25, 2009 #1
    1. The problem statement, all variables and given/known data

    Can someone advice me how to solve this square root equation?
    [tex]n_{0}=1.5*10^{15}+\sqrt{(1.5*10^{15})^{2}+[(0.05)n_{0}]^{2}}[/tex]

    The answer should be n0=3.0075*1015

    I can't figure out how to open up the square root to solve the equation for n0.
    Stuck here staring at the equation....

    Isolate the square root on one side of the equals sign, then square both sides.

    solved. but must take note to make the equation:

    [n0-(1.5*1015)]2=(1.5*1015)2+0.0025n02

    Thanks and cheers
