Hi! what’s the question? i believe you only put two answers
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:


Answer:
Step-by-step explanation:
Three ways are:
<u>In Fraction Form:</u>
<u>In Ratio its</u>: What you said
7:30 And
In a Percent Form Its:

Hope IT helped You. :D
64,000 I believe. What I did was find the area so 4*4 =16. 1000/16 = 62.5 earthworms per square foot. So if the side is 8 times longer then 8*4= 32 feet per side and to find the area of that it's 32*32 = 1024 feet squared. So 62.5 * 1024 =64,000
