Answer:
5
Step-by-step explanation:
First, let us simplify the expression on the left
8(4+3) - 21 = 8(7) - 21 = 8(7) - 3(7) = 7(8-3)
Divide this by 7 and you'll get 8-3 = 5
Answer:
<u><em>8(cos270° + i sin270°)</em></u>
Step-by-step explanation:
(cos(a) + i * sin(a)) * (cos(b) + i * sin(b)) = cos(a + b) = i * sin(a + b)
2 * 4 * (cos(270) + i * sin(270))
8(cos270° + i sin270°)
Answer:
Step-by-step explanation:
i^3= -i
i^4= 1
i^5= i
i^6= -1
i^7= -i
For the other questions, can you give me the value of N. If that is not possible, then sorry I can not help you. And feel free to report this if this is not useful :(
