If `sqrt(a)=sqrt(b)+sqrt(c) and sqrta ,sqrt(b)) and sqrt(c)` are there surds , then

If sqrt(m)-sqrt(a)+sqrt(c) and sqrt(m), sqrt(a), and sqrt(c) are three surds, their

sqrt(75) and sqrt(147) are like surds

sqrt(150) and sqrt(180) are ______ surds

sqrt(192) and sqrt(147) are ________ surds

(a+c sqrt(b))(2+y sqrt(b))

Q.Which of the following is/are always true? (a) Every irrational number is a surd.(b) Any surd of the form n sqrt(a)+n sqrt(b) can be rationalised by a surd of the form (n sqrt(a)-n sqrt(b)) a where n sqrt(a) and n sqrt(b) are surds.(c) Both (a) and (b) Neither (a) nor (b)

If a+sqrt(b)=c+sqrt(d) where a and c are rational numbers sqrt(b) and sqrt(d) are irrational numbers then prove that a=c and b=d .

if (4)/(2+sqrt(3)+sqrt(7))=sqrt(a)+sqrt(b)-sqrt(c) then :

Evaluate : ( sqrt(a) + sqrt(b) ) ( sqrt(a) - sqrt(b) )

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