sqrt(8) * sqrt(18)
= sqrt(4) * sqrt(2) * sqrt(9) * sqrt(2)
= 2 * 3 * sqrt(2) * sqrt(2)
= 6 * 2
= 12.

sqrt 8 = 2sqrt2
sqrt 18 = 3sqrt2
then 2sqrt2 x 3 sqrt 2
= 2*2*3
= 12

sqrt ( 8 ) * sqrt (18)
= sqrt ( 2 * 4 ) * sqrt ( 2 * 9 )
= 2 * sqrt (2) * 3 sqrt (2) << cuz we know the sqrt of 4 and 9
= 6 * sqrt (2) * sqrt (2)
= 6 * 2 << cuz (sqrt (2) * sqrt (2) = 2)
= 12
i never thought the result would be an integet lol

Faactor the numbers under each root sign to give you sqrt(2x2x2) x sqrt(2x3x3). The rule for multiplying square roots like this is that you can put all the factors under one root sign. That gives you sqrt(2x2x2x2x3x3). You can now take out two 2's and one 3 to give you the answer - 2x2x3 = 12.

first multiply the sqrt (one million/2) into the paranthesis sqrt (one million/2) * sqrt (8) = sqrt (4) = 2 sqrt (one million/2) * sqrt (2) = sqrt (one million) = one million so which you get (sqrt(4) + sqrt(one million)) = 3 3 is the simplified
