simplify-3i^4+2i^3+2i^2+sqrt(-9)

simplify

- 3 i^{4} + 2 i^{3} + 2 i^{2} + - 9

- 5 + i

Solution steps

- 3 i^{4} + 2 i^{3} + 2 i^{2} + - 9

- 3 i^{4} = - 3

2 i^{3} = - 2 i

2 i^{2} = - 2

- 9 = 3 i

= - 3 - 2 i - 2 + 3 i

Group like terms

= - 2 i + 3 i - 3 - 2

Add similar elements:

- 2 i + 3 i = i

= i - 3 - 2

Subtract the numbers:

- 3 - 2 = - 5

= i - 5

Rewrite in standard complex form:

- 5 + i

= - 5 + i

9 + 2 c = 43

x - 8 \geq 5

- 5 (3 - a) = - 3 (2 - a)

b (b + 17) = 0

y + 11 = 22
