We will break this down into its parts:
We know that this is a fraction where the numerator is √(-1) = i
The denominator:
4 - 3i - (2 + 5i); we put 2 + 5i in brackets because we are to subtract its quantity.
Simplifying the denominator:
4 - 3i - 2 - 5i
= 2 - 8i
Now, we write the expression in fractional form:
i / (2 - 8i)
To remove an imaginary number from the denominator, we multiply and divide by its conjugate. The conjugate of a + bi is a - bi
i(2 + 8i) / (2² - (8i)²)
= (-8 + 2i) / (4 + 64)
= -2/17 + i/34

Answer:
760 rods.
Step-by-step explanation:
If my memory serves me right there are 4 rods in a chain and 10 chains in a furlong.
So 19 furlongs = 19 * 10 * 4 rods
= 760 rods.
Answer:
an answer for what? This one doesn't have a question
Cylindervolume=hpir^2
V=432
432=hpir^2=original
if each is divided by 3 then
h turns to (1/3)h
r turns to (1/3)r
input and find the effect
(1/3)hpi[(1/3)r]^2
(1/3)hpi(1/9)r^2
move 1/9 to front
(1/27)hpir^2
compared to original volume (which was hpir^2)
so therefor we multiply the original volume by 1/27
432*1/27=16
the new volume is 16 cubic meters
