Please post an example of what you are having trouble with and your attempt to solve it.
By the way when you do, please write square root of x as sqrt(x)
and a cube root or fourth root as x^(1/3) or x^(1/4). hen we will undertand what you mean.

. 3/[SQRT(5) - 2]
Simplify.
Answered by Damon
multiply top and bottom by (sqrt(5) + 2 )

.3 [sqrt(5)+2]/ {[ sqrt (5) -2][sqrt(5) +2] }

= (.3 sqrt(5) +.6)/ (5-4)

= .3 sqrt(5) + .6

Can you do the same with this?
3b[SQRT(27a5b)] + 2a[SQRT(3a3b3)]
Answered by Mike
3b[SQRT(27a^5b)] + 2a[SQRT(3a^3b^3)]
Answered by Damon
3 b sqrt ( 3*9 a a^4 b) + 2a sqrt (3 a a^2 b b^2)

3 b 3 a^2 sqrt(3 a b) + 2 a a b sqrt(3 a b)

9 a^2 b sqrt (3 a b) + 2 a^2 b sqrt (3 a b)

11 a^2 b sqrt (3 a b)
