`x+y={:[(2,1),(1,2)],2x-y=[(1,2),(2,1)]:}`, तो x को ज्ञात कीजिए ।

यदि (x/3+1,y-2/3) = (5/3,1/3) हो, तो x और y का माना ज्ञात , कीजिये।

If 9x^2+y^2=37 and xy = 2 , x, y> 0 , then the value of (27x^3+y^3) is : यदि 9x^2+y^2=37 और xy = 2 , x, y> 0 , तो (27x^3+y^3) का मान ज्ञात कीजिए ।

If 3x^2-5x+1=0 , then the value of (x^2+ 1/(9x^2)) is : यदि 3x^2-5x+1=0 , तो (x^2+ 1/(9x^2)) का मान ज्ञात कीजिए ।

If 2=x+1/(1+1/(5+1/2)) , then the value of x is equal to: यदि 2=x+1/(1+1/(5+1/2)) , तो x का मान ज्ञात करें:

if (x_(1),x_(2))^(2)+(y_(1)-y_(2))^(2)=a^(2), (x_(2)-x_(3))^(2)+(y_(2)-y_(3))^(2)=b^(2) (x_(3)-x_(1))^(2)+(y_(3)-y_(1))^(2)=c^(2). where a,b,c are positive then prove that 4 |{:(x_(1),,y_(1),,1),(x_(2) ,,y_(2),,1),( x_(3),, y_(3),,1):}| = (a+b+c) (b+c-a) (c+a-b)(a+b-c)
