\frac{\sqrt{2} - \sqrt{2} i}{2} = {(\frac{\sqrt{2}}{1 - i})}^{x}

$\frac{\sqrt{2} - \sqrt{2} i}{2} = {(\frac{\sqrt{2}}{1 - i})}^{x}$

Step 1

Rewrite the equation as

{(\frac{\sqrt{2}}{1 - i})}^{x} = \frac{\sqrt{2} - \sqrt{2} i}{2}

${(\frac{\sqrt{2}}{1 - i})}^{x} = \frac{\sqrt{2} - \sqrt{2} i}{2}$ .

{(\frac{\sqrt{2}}{1 - i})}^{x} = \frac{\sqrt{2} - \sqrt{2} i}{2}

${(\frac{\sqrt{2}}{1 - i})}^{x} = \frac{\sqrt{2} - \sqrt{2} i}{2}$

Step 2

Take the natural logarithm of both sides of the equation to remove the variable from the exponent.

\ln ({(\frac{\sqrt{2}}{1 - i})}^{x}) = \ln (\frac{\sqrt{2} - \sqrt{2} i}{2})

$\ln ({(\frac{\sqrt{2}}{1 - i})}^{x}) = \ln (\frac{\sqrt{2} - \sqrt{2} i}{2})$
