For the numbers in
form, convert to polar form:

By DeMoivre's theorem,





For the numbers already in polar form, DeMoivre's theorem can be applied directly:


At second glance, I think the 2s in the last two numbers should also be getting raised to the 3rd and 4th powers:

0.7 Liters and 0.70 Liters are the same amount.
You can think of them as fractions: 7/10 and 70/100. Both of these mean the same. 7/10 is the simplest form of the number.
When you put zeros to the right of any number that is to the right of the decimal point, it will not change the value of the number.
0.7 L = 0.70 L

Answer: a) -13/16
Step-by-step explanation: Start by setting equations equal and rearrange X^3 - x^2 + 1 = 0. Visual inspection of graph shows x between -1 and -1/2. Start with x = 3/4 plug in and calculate: just a little too small. Try going halfway towards -1: x =-7/8 Plug in and the answer is very far from 0. Go halfway back towards -3/4: -13/16 and the equality is very close.
