<PRE><B>Question 252924</B>
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)
{{{sqrt(5)*(2sqrt(10) + sqrt(2x))}}}
By distributive property, we get
{{{2*sqrt(50) + sqrt(10x)}}}
but sqrt(50) = 5sqrt(2), so, we get
{{{10sqrt(2) + sqrt(10x)}}}
3. (2-square root of 6)(1 + square root of 6) 
{{{(2-sqrt(6))*(1+sqrt(6))}}}
here we will foil
2 + 2sqrt(6) - sqrt(6) -sqrt(36)
combine like terms, remember that sqrt(36) = 6.
8 + sqrt(6).</PRE>
