simplify sqrt(9)-sqrt(-2)+sqrt(64)+sqrt(-18)

simplify

9 - - 2 + 64 + - 18

11 + 22 i

Solution steps

9 - - 2 + 64 + - 18

9 = 3

- 2 = 2 i

64 = 8

- 18 = 2 \cdot 3 i

= 3 - 2 i + 8 + 2 \cdot 3 i

Group like terms

= - 2 i + 2 \cdot 3 i + 3 + 8

Add similar elements:

- 2 i + 2 \cdot 3 i = 22 i

= 22 i + 3 + 8

Add the numbers:

3 + 8 = 11

= 22 i + 11

Rewrite in standard complex form:

11 + 22 i

= 11 + 22 i
