    I dont see how thats possible

    12/sqrt2 * sqrt 2 / sqrt 2

    = 12 sqrt 2 / 2

    =6sqrt2

    you multiply it by sqrt 2 / sqrt 2 because that also equals to 1, therefore, u r not really doing anything to the original number.

    i hope this helps :D

    12/sqrt2

    Multiplying both numerator and denominator with sqrt2,we get

    12*sqrt2/sqrt2*sqrt2=12*sqrt2/2

    because sqrt2*sqrt2=sqrt(2*2)=sqrt(4)=2

    12*sqrt(2)/2=6*sqrt(2)

    well,

    try mutiplying 12/sqrt(2) with sqrt(2)/sqrt(2) (which is 1)

    you'll get 12sqrt(2)/2 = 6sqrt(2)
