If `( ( sqrta + sqrtb ) /( sqrta - sqrtb ) )^2` = `3/1` , then find `a/b`

(a + b)(sqrta + sqrtb ) (sqrta - sqrtb)= "________"

If (sqrta+sqrtb)=17 and (sqrta-sqrtb)=1 , then the value of sqrtab is :

If sqrtx + sqrty = sqrta " then " (dy)/(dx) = ?

sqrt(a +b -2 sqrt(ab)) is ____ where sqrta gt sqrtb

If x = (4 sqrt(ab))/(sqrt a + sqrt b) , then what is the value of (x + 2sqrt a)/(x - 2 sqrta) + (x + 2 sqrtb)/(x - 2 sqrt b) " (when " a ne b) ?

If sqrt(9+sqrt48-sqrt32-sqrt24)=sqrta-sqrtb+2 ,where a,b inN , then find the value of a + b.

If y = tan^(-1) ((sqrta + sqrtx)/(1 - sqrt(ax))) " then " (dy)/(dx) = ?

If (3a+2b) : (5a+7b) = 1:2 , then find a : b.
