The correct simplifications of powers of i are:
a. i^27=−i
d. i^8=1
e. i^5=i
Step-by-step explanation:
We know that
We can use the smaller powers of i to solve the larger powers.
a. i^27=−i
b. i^28=i
c. i^14=1
d. i^8=1
e. i^5=i
Hence,
The correct simplifications of powers of i are:
a. i^27=−i
d. i^8=1
e. i^5=i

X is equal to 7. Since you are trying to make them equal to each other, the denominator is already the same, so you just need to make the numerator the same too.
Answer:
C. $70.00
Step-by-step explanation:
First convert the discount rate of 60% into a decimal (0.6)
Remember that the original price(x) times the discount rate(0.6) is the sale price(42).
0.6x=42
divide both sides by 0.6 to get
x=70
The original price was $70.00
