4sqrt2

Explanation:

A simplified version will be of the form asqrtb " where a is a rational number"

Note : sqrta xx sqrta = a : "example" sqrt100 xx sqrt100 = 10 xx 10 = 100

To simplify this expression multiply numerator and denominator by sqrt2

hence ( 8sqrt2)/(sqrt2 xx sqrt2)=( 8sqrt2)/2 = 4sqrt2
