simplify 4i^3-2i^2+1

Solution

simplify

4 i^{3} - 2 i^{2} + 1

Solution

3 - 4 i

Solution steps

4 i^{3} - 2 i^{2} + 1

4 i^{3} = - 4 i

2 i^{2} = - 2

= - 4 i - (- 2) + 1

Apply rule:

a - (- b) = a + b

- 4 i - (- 2) = - 4 i + 2

= - 4 i + 2 + 1

Add the numbers:

2 + 1 = 3

= - 4 i + 3

Rewrite in standard complex form:

3 - 4 i

= 3 - 4 i
