I need some help with my radical equations. I would really appreciate some aassistance.
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.
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)]
3b[SQRT(27a^5b)] + 2a[SQRT(3a^3b^3)]
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)
