2^(1/x)
Detail solution
  1. Let u=1xu = \frac{1}{x}.

  2. ddu2u=2ulog(2)\frac{d}{d u} 2^{u} = 2^{u} \log{\left(2 \right)}

  3. Then, apply the chain rule. Multiply by ddx1x\frac{d}{d x} \frac{1}{x}:

    1. Apply the power rule: 1x\frac{1}{x} goes to 1x2- \frac{1}{x^{2}}

    The result of the chain rule is:

    21xlog(2)x2- \frac{2^{\frac{1}{x}} \log{\left(2 \right)}}{x^{2}}


The answer is:

21xlog(2)x2- \frac{2^{\frac{1}{x}} \log{\left(2 \right)}}{x^{2}}
