Answer:
6.5e^(i·(-157.38°)) ≈ 6.5e^(-2.7468i)
Step-by-step explanation:
A suitable calculator can find the value of this ratio for you.
((2+3i)/(1-i))² = -6 -2.5i ≈ 6.5∠-157.38° ≈ 6.5e^(-2.7468i)
__
The second attachments shows the calculator set to radian mode for the angle measure.
Answer:
see the explanation
Step-by-step explanation:
Remember that
A proportion is the ratio (quotient) between two numbers
so
Twelve hundredths to three is ----> 
Twenty-four hundredths to eight ----> 
therefore
Twelve hundredths is to three as twenty-four hundredths is to eight

Note The proportion is not true
