Let `a,b in R. sqrta sqrtb = sqrt(ab)` is not true if

(sqrta + sqrtb)^2 = ?

(sqrta+b)(sqrta-b) =

In a triangle ABC, sqrta+sqrtb-sqrtc is

(sqrta+sqrtb)(sqrta -sqrtb) =__

If sqrta : sqrtb = sqrt3 : sqrt2 " and " sqrtb : sqrtc = sqrt3 : sqrt2 , then find the value of (sqrta + sqrtb ) : ( sqrtb + sqrtc) .

If a 0, then sqrta. sqrtb is equal to :

If a>0,b>0 then sqrt(-a) . sqrtb is equal to

If a,b in R such that ab gt 0 , then sqrt(a)sqrt(b) is equal to

If a,b in R such that ab gt 0 , then sqrt(a)sqrt(b) is equal to
