" यदि "(x)/(y)=(1)/(3)" हो,तो "(x^(2)+y^(2))/(x^(2)-y^(2))=?

If (2x-y) : (5x+3y) = 3:8, then find the value of (x^2+y^2) : (x^2-y^2) . यदि (2x-y) : (5x+3y) = 3:8 है, तो (x^2+y^2) : (x^2-y^2) का मान ज्ञात करें |

If x and y are of same sign,then the value of (x^(3))/(2)cos ec^(2)((1)/(2)(tan^(-1)x)/(y))+(y^(3))/(2)sec^(2)((1)/(2)(tan^(-1)y)/(x)) is equal to (x-y)(x^(2)+y^(2)) (b) (x+y)(x^(2)-y^(2))(x+y)(x^(2)+y^(2))*(d)(x-y)(x^(2)-y^(2))

(x+y)^(3)-(x-y)^(3) can be factorized as 2y(3x^(2)+y^(2)) (b) 2x(3x^(2)+y^(2))2y(3y^(2)+x^(2)) (d) 2x(x^(2)+3y^(2))

If (5x+2y) : (10x+3y) = 5:9 , then (2x^2+3y^2 ):(4x^2+9y^2) =? यदि (5x+2y) : (10x+3y) = 5:9 , है, तो (2x^2+3y^2 ): (4x^2+9y^2) =?

"Find the value of "(x+y)," if "(x+(y^(3))/(x^(2)))^(-1)-((x^(2))/(y)+(y^(2))/(x))^(-1)+((x^(3))/(y^(2))+y)^(-1)=(1)/(3)

If x = a +1/a and y=a-1/a then sqrt(x^4+ y^4-2x^2y^2) is equal to : यदि x = a +1/a और y=a-1/a है, तो sqrt(x^4+ y^4-2x^2y^2) का मान किसके बराबर होगा?

Find the value of (x+y) ,if (x+(y^(3))/(x^(2)))^(-1)-((x^(2))/(y)+(y^(2))/(x))^(-1)+((x^(3))/(y^(2))+y)^(-1)=(1)/(3)

The factors of x^(3)-1+y^(3)+3xy are (a) (x-1+y)(x^(2)+1+y^(2)+x+y-xy)( b) (x+y+1)(x^(2)+y^(2)+1-xy-x-y)( c) (x-1+y)(x^(2)-1-y^(2)+x+y+xy)(d)3(x+y-1)(x^(2)+y^(2)-1)

If the circle x^(2)+y^(2)=a^(2) intersects the hyperbola xy=c^(2) in four points P (x_(1) ,y_(1)) Q (x_(2), y_(2)) R (x_(3) ,y_(3)) S (x_(4) ,y_(4)) then 1) x_(1)+x_(2)+x_(3)+x_(4)=2c^(2) 2) y_(1)+y_(2)+y_(3)+y_(4)=0 3) x_(1)x_(2)x_(3)x_(4)=2c^(4) 4) y_(1)y_(2)y_(3)y_(4)=2c^(4)
