If x is so small such that its square and digher powers may be neglected then find the appoximate value of `((1-3)^(1//2)+(1-x)^(5//3))/(4+x)^(1//2)`

Explanation

To find the approximate value of the expression

\[ \frac{(1-3x)^{1/2} + (1-x)^{5/3}}{(4+x)^{1/2}} \]

when \( x \) is very small (and thus \( x^2 \) and higher powers can be neglected), we can use the binomial expansion.
