make x subject y equals x over 4 subtracted by 2
x + y = 4
x^5 + y^5 = 464
find value of x and y
$\sqrt{\48}$
\left(\frac{\left(\sqrt{2^2+4}\right)^5}{5}-\frac{4\left(\sqrt{2^2+4}\right)^3}{3}\ \right)-\left(\frac{\left(\sqrt{0^2+4}\right)^...
2.5+j4
2/x + 5/y = 2
3/x - 2/y = 6
Find the value of x. 2:4:: 8: x
If u=f(x, y) then with usual notations, Uxy=Uyx if:-
1)Ux is continuous
2) u, ux, uy are continuous
3)
u is continuous​
y(x+1)=(x^(2)+2x) dy/dx
what is rational number?
