`(a-b)=?`
`(a) sqrta`
`(b) sqrtb`
`(c) sqrta-sqrtb`
`(d) (sqrta-sqrtb)(sqrta+sqrtb)`

(sqrta + sqrtb)^2 = ?

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

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

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

If sqrt(10-2 sqrt21)+ sqrt(8+2 sqrt15)= sqrta+ sqrt b , where a and b are positive integers, then the value of sqrt(ab) is closest to : यदि sqrt(10-2 sqrt21)+ sqrt(8+2 sqrt15)= sqrta+ sqrt b है, जहाँ a और b धनात्मक पूर्णाक है, तो sqrt(ab) का मान ( लगभग ) ज्ञात करें |

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

If a=(sqrt5+sqrt10)/(sqrt10-sqrt5) and b=(sqrt10-sqrt5)/(sqrt10+sqrt5) show that sqrta-sqrtb-2sqrt(ab)=0
