multiply and simplify. show your steps.
1. square root of 15b
there is nothing to multiply by so I cannot answer 1.
--
2. square root of 5(2 square root of 10+ square root of 2x)
By distributive property, we get
but sqrt(50) = 5sqrt(2), so, we get
3. (2-square root of 6)(1 + square root of 6)
here we will foil
2 + 2sqrt(6) - sqrt(6) -sqrt(36)
combine like terms, remember that sqrt(36) = 6.
8 + sqrt(6).

1. square root of 15b
Nothing to do.
-----------------
2. square root of 5(2 square root of 10+ square root of 2x)
sqrt(5)*(2sqrt(10) + sqrt(2x))
= 2sqrt(50) + sqrt(10x)
= 10sqrt(2) + sqrt(10x)
-----------------
3. (2-square root of 6)(1 + square root of 6)
= 2 - 6 + sqrt(6)
= -4 + sqrt(6)
