If `3x^2 + 5y^2 + 4z^2-sqrt15 xy-2sqrt5 yz-2sqrt3 xz=0` then the value of `3x^2+5y^2 +16z^2-8sqrt5 yz+2sqrt15 xy-8sqrt 3 xz` is

If 2x^2+y^2+8z^2-2 sqrt2 xy+4 sqrt2 yz-8zx=(Ax+y+Bz)^2 , then the value of (A^2+B^2-AB) is: यदि 2x^2+y^2+8z^2-2 sqrt2 xy+4 sqrt2 yz-8zx=(Ax+y+Bz)^2 है, तो (A^2+B^2-AB) का मान होगा ?

If x=3sqrt(5)+2sqrt(2) and y=3sqrt(5)-2sqrt(2) , then the value of (x^(2)-y^(2))^(2) is

If 5 sqrt5 x^3-81 sqrt3 y^3 div sqrt5 x-3 sqrt3 y=Ax^2+By^2+Cxy , then the value of (6A+B-sqrt15 C) is: यदि 5 sqrt5 x^3-81 sqrt3 y^3 div sqrt5 x-3 sqrt3 y=Ax^2+By^2+Cxy है, तो (6A+B-sqrt15 C) का मान ज्ञात करें |

If x= (sqrt5+1)/(sqrt5-1) and x = 1/y then find the value of (3x^(2) -7xy + 3y^(2))
