Answer
$2^{\wedge}(3-x)/(1-2^{\wedge}x)$
Work Step by Step
$2^{\wedge}(3-x)/(1-2^{\wedge}x)$
or
$(2^{\wedge}(3-x))/(1-2^{\wedge}x)$
There is no real need to enclose the numerator in parentheses, because $2^{\wedge}(3-x)$ is one term.
The denominator must be enclosed in parentheses,
and the exponent must be enclosed in parentheses,
otherwise, for example,
$2^{\wedge}3-x/1-2^{\wedge}x \quad $ generates $2^{3}-\displaystyle \frac{x}{1}-2^{x}$,
$(2^{\wedge}3-x)/1-2^{\wedge}x \quad $ generates $\displaystyle \frac{2^{3}-x}{1}-2^{x}$,
$2^{\wedge}(3-x)/1-2^{\wedge}x \quad $ generates $\displaystyle \frac{2^{3-x}}{1}-2^{x}$, etc.
