convert 24 and 3/8 to improper fraction
24 and 3/8=24+3/8=192/8+3/8=195/8
195/8 times number of pieces=1200
times bothsides by 8/195 to clear fraction (195/8 times 8/195=1560/1560=1)

Please Help!!<br><br> Write in exponential form.
Karo-lina-s [1.5K]

ANSWER

c.

5{e}^{i  \frac{5\pi}{3} }

EXPLANATION

The exponential form of complex numbers is given by;

z =r  {e}^{i \theta}

The given complex number in polar form is:

5( \cos( \frac{5\pi}{3} + i \sin( \frac{5\pi}{3})  )

We have r=5 from the question and

\theta =  \frac{5\pi}{3}

We substitute these values to obtain the exponential form:

z =5{e}^{i  \frac{5\pi}{3} }

The correct answer is C
