For the complex numbers z =30(cos(2pi/3)+isin(2pi/3) and w=6(cos(pi/8)+isin(pi/8) which geometric transformation of z on the dimples plane describes z/w

I'm terrible at math any here is appreciated.

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per day. there are 3.65 \cdot 10^23.65⋅10 2 3, point, 65, dot, 10, start superscript, 2, end superscript days in one year.how many times does the heart beat in one year? write your answer in scientific notation, and round to one decimal place.

The sum of the reciprocal of a positive number and the reciprocal of 2 more than the number is 3/4 equation: the number is
