If a and b are positive natural numbers `(sqrta + sqrtb)(sqrtc+sqrtd) = sqrt(ac) + sqrt(ad)+sqrt(bc)+sqrt(bd)`

If a and b are positive natural numbers (sqrt(a)+sqrt(b))(sqrt(c)+sqrt(d))=sqrt(ac)+sqrt(ad)+sqrt(bc)+sqrt(bd)

If a and b are positive natural numbers (sqrt(a)+sqrt(b))(sqrt(a)-sqrt(b))=a-b

If a and b are rational numbers and (sqrt(2)+2sqrt(3))/(2sqrt(2)+sqrt(3))=a+b sqrt(6)

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

If m and n are natural numbers such that sqrt(7+sqrt(48))=sqrt(m)+sqrt(n) then m^(2)+n^(2)=

If a,b,c are positive unequal real numbers then prove that sqrt14+sqrt7gtsqrt16+sqrt5 .

The conjugate surd of sqrt(a)+b is sqrt(a)-b b- "sqrt(a) sqrt(a)+sqrt(b) sqrt(a)-sqrt(b)

Suppose a,b are positive real numbers such that a sqrt(a)+b sqrt(b)=183 and a sqrt(b)+b sqrt(a)=182 then find ((9)/(5))(a+b)

If sqrt(a)>sqrt(b)>sqrt(c)>sqrt(d) where a,b,c and d are consecutive natural numbers then which of the following is correct (1)sqrt(a)-sqrt(b)>sqrt(c)-sqrt(d)(2)sqrt(c)-sqrt(d)>sqrt(a)-sqrt(b)(3)sqrt(a)-sqrt(c)>sqrt(b)-sqrt(d)(4)sqrt(c)-sqrt(d)=sqrt(a)-sqrt(b)

If n is a natural number, then sqrt(n) is:
