" 11."x^(y)+y^(x)=a^(b)

Factorise : x^(4)-11x^(2)y^(2)+y^(4)

If x:y=3:1, then backslash x^(3)-y^(3):x^(3)+y^(3)=?10:11 b.11:10 c.13:14 d.14:13

If e[(e^(x),e^(y)),(e^(y),e^(x))]=[(1,1),(1,1)] , then the values of x and y are respectively

If {:[(e^x,e^y),(e^y, e^x)]=[(1,1),(1,1)] , then the values of x and y are respectively

Verify the property: x\ "x"\ y=y\ "x"\ x\ b y\ t a k ing: x=-1/3, y=2/7 (ii) x=(-3)/5, y=(-11)/(13)

If x^(11)=y^(0) and x=2y , then y is equal to

Find y 'x for the following implicit function (a) y=x +arc tan y (b) x^(2)+5xy+y^(2)-2x+y-6=0 find y'' at the point (1,1)

If x:y=1:1, then (3x+4y)/(5x+6y)=(7)/(11) (b) (17)/(11)(17)/(23)(d)(4)/(5)
