4sqrt(2)

Explanation:

We must use our knowledge of surds:

sqrt(a*b) = sqrt(a)*sqrt(b)

=> sqrt(6) = sqrt(2*3) = sqrt(2) * sqrt(3)

(8sqrt(6))/(2sqrt(3)) = (8sqrt(2)*sqrt(3))/(2sqrt(3) )

We can cancel out the sqrt(3) as on both numerator and denominator:

(8sqrt(2)*cancel(sqrt(3)))/(2cancel(sqrt(3) ) ) = (8sqrt(2) )/ 2

We know 8/2 = 4

=> 4sqrt(2)
