how do i start this problem

[kkiceman14]

Simplify:

1/ squrt3 + squrt 3

 

[Euler]

Perhaps they just want

1/2sqrt(3)?

 

[kkiceman14]

i don't understand that

 

[pka]

$\displaystyle \frac{1}{{\sqrt 3 }} = \frac{{\sqrt 3 }}{3}$

$\displaystyle \frac{{\sqrt 3 }}{3} + \sqrt 3 = \frac{{4\sqrt 3 }}{3}$

 

[Denis]

Simplify:
1/ squrt3 + squrt 3

show them things like this: sqrt(3); OK?

1/sqrt(3) + sqrt(3)
= [1 + sqrt(3)sqrt(3)] / sqrt(3) : lcd
= (1 + 3) / sqrt(3)
= 4 / sqrt(3)
