Answer» Correct Answer - A `((a^(x^(4)))/(a^(y^(4))))^((1)/(x^2+y^2))xx(a^(y^(4))/(a^(z^4)))^((1)/(y^2+z^2))xx((a^(z^(1)))/(a^(x^(4))))^((1)/(z^2+x^2))` `=(a^(x^(4)))^((1)/(x^2+y^2))xx(a^(y^(4-z^4)))^((1)/(y^2+z^2))xx(a^(z^(4-x^4)))^((1)/(z^2+x^2))` `=a((x^2-y^2)(x^2+y^2))/(x^3+y^2)xxa((y^2-z^2)(y^2+z^2))/(y^3+z^2)xxa((z^2-x^2)(z^2+x^2))/(z^3+x^2)` `=a^(x^2-y^2+y^2-z^2+z^2-x^2)=a^0=1` Hence , the correct option is (a). |
