Find the value of $(x+y)$ ,if ${(x+\frac{y^3}{x^2})}^{-1}-{(\frac{x^2}{y}+\frac{y^2}{x})}^{-1}+{(\frac{x^3}{y^2}+y)}^{-1}=\frac{1}{3}$

If $(x+1,y-2)=(3,-1)$, find the values of x and y.

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 $(x+1,1)=(3,y-2)$, find the value of $x$ and $y$.

The value of (x+y)(x-y)+1/(2!)(x+y)(x-y)(x^2+y^2)+1/(3!)(x+y)(x-y)(x^4+y^4+x^2y^2)+ ... is :

x+y=2 এবং 1/x+1/y=2 হলে $x^3+y^3$ এর মান হিসাব করে লেখো?

(x-y)/(x)+1/2((x-y)/(x))^(2)1/3((x-y)/(x))^(3)+. . . . is equal to

यदि $x-y=11$ और $\frac{1}{x}-\frac{1}{y}=\frac{11}{24}$ है, तो $x^3-y^3+x^2{y}^2$ का मान ज्ञात करें।

यदि $x+y=2$ और $\frac{1}{x}+\frac{1}{y}=\frac{18}{5}$ है तो $(x^3+y^3)$ का मान ज्ञात करें।
