7sqrt(2)/2 722

Explanation:

First, we cancel off 5 and 10,
since they shared the same common factor (5).

5xx1=55×1=5
5xx2=105×2=10

cancel(5)1sqrt2(7/(cancel(10)2))

Rearrange;

sqrt(2)xx(7/2)=7sqrt(2)/2

Note that 1 is negligible
since anything multiply with 1 we get the same answer.

Thank you. Hope it help.
