Please help! Express the following in the formx + iy

(i)(8 + 6i) + (6 + 4i)
(ii) (9 - 3i) + (- 4 + 5i)
(iii )(2+7i)-(5+3i)
(iv)(5-i)-(6-2i)
(V) 3(4 + 6i) + 9(1 - 2i)
(vi) 3i^ * (7-4i)
( ii)(9+2i)(1+3i)
( viii)(4-i)(3+2i)
(ix)(7+3i) ^ 2
(x)(8 + 6i) (8 - 6i)
(xi)(1+2i)(3-4i)^ (5+6 )
(Xii)(3+2i)^3

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

ya

a) is $10.34

b) is 6 toppings
