8√5 - 10√(1/5) = 8√5 - 10/√5 = 8√5 - 10√5/5
= 8√5 - 2√5 = 6√5

radical(1/5) = radical((1*5)/(5*5)) = radical(1*5)/radical(5*5) = radical(5)/5

8 * sqrt(5) - 10 * sqrt(1/5) = 8 sqrt(5) - 10 / sqrt(5)
= (8 sqrt(5) sqrt(5)) / sqrt(5)) - 10 / sqrrt(5)
= (8 * 5 - 10) / sqrt(5)
= 30 / sqrt(5)
= 6 * 5 / sqrt(5)
= 6 * sqrt(5)
