Answer:
-625
Step-by-step explanation:
The magnitude gets raised to the power, and the angle gets multiplied by the power:
5(cis7pi/4)^4 = (5^4)cis(4·7π/4) = 625cis(7π) = 625cis(π) = -625
4 + 2 + 7 = 13
7/12 + 3/4 + 5/12 = 7/12 + 9/12 + 5/12 = 21/12 = 1 9/12 = 1 3/4
13 + 1 3/4 =
14 3/4 <===

Answer:
k > 7
Step-by-step explanation:
Given the inequality statement: 4k - (5 + 3k) > 2
Distribute -1 into (5 + 3k):
4k -5 - 3k > 2
Next, add like terms:
k - 5 > 2
Add 5 to both sides of the inequality:
k - 5 + 5 > 2 + 5
k > 7
