Determine the value of the following complex number power. Your answer will be plotted in orange.

 (\color{BLUE}{BASE_REP}) ^ {EXPONENT} 
graphInit({ range: [ [-5, 5], [-5, 5] ], scale: 30, tickStep: 1, axisArrows: "<->" }); drawComplexChart( 5, DENOMINATOR ); circle( [ BASE_REAL, BASE_IMAG ], 1 / 4, { fill: KhanUtil.BLUE, stroke: "none" }); graph.currComplexPolar = new ComplexPolarForm( DENOMINATOR, 5, EULER_FORM ); redrawComplexPolarForm();

All powers of 1 are 1.

Let's express our complex number in Euler form first.

 \color{BLUE}{BASE_REP} = \color{BLUE}{BASE_EULER_REP} 

Since (a ^ b) ^ c = a ^ {b \cdot c},  (\color{BLUE}{BASE_EULER_REP}) ^ {EXPONENT} = e ^ {EXPONENT \cdot (BASE_E_EXPONENT)} 

The angle of the result is EXPONENT \cdot BASE_ANGLE_REP, which is ANGLE_MULTIPLE_REP.

ANGLE_MULTIPLE_REP is more than 2 \pi. It is a common practice to keep complex number angles between 0 and 2 \pi, because e^{2 \pi i} = (e^{\pi i}) ^ 2 = (-1) ^ 2 = 1. We will now subtract the nearest multiple of 2 \pi from the angle.

 ANGLE_MULTIPLE_REP - NEAREST_TWO_PI_MULTIPLE = ANSWER_ANGLE_REP 

Our result is ANSWER_EULER.

Converting this back from Euler form, we get ANSWER.
