    \[(40/\sqrt{2}) *(\sqrt{2}/\sqrt{2})\] Simply by multiplying by a number over itself is a clever way of changing a number into a slightly different form. You can do this because any number divided by itself equals 1, just like 5*1=5.

    ...so the answer is that 40/sqrt2 becomes 8sqrt2 by multiplying by 2/5 :P
