Answer:

You look for numbers that can be found both on the denominator, and on the numerator.

Explanation:

Your expression looks like this

#(2sqrt(2))/(8sqrt(2))#

RIght from the start, #sqrt(2)# will cancel out because you have in both the numerator, and in the denominator.

The resulting fraction will be

#(2 * cancel(sqrt(2)))/(8 * cancel(sqrt(2))) = 2/8#

Now, you know that #8# can be written as

#8 = 4 * 2#

which means that the fraction becomes

#cancel(2)/(cancel(2) * 4) = color(green)(1/4)#
