What is the simplified form of the above?

• 7/10 + 11i/10

• 13/10 +i/10

• 5/4 - 3i/2

• 7/10 - 11i/10

(3 + 2i) + (4 - 5i)

• 7 + 7i

• 1 - 3i

• 1 - 7i

• 7 - 3i

(-7 + 9i) + (2 - 10i)

• -5 + i

• -5 - i

• -9 + 1

• 9 - i

Simplify
3i - (4 + 7i)

• -4 + 10i

• 21 - 12i

The expression (2 + 3i)² is equal to

• -5

• -5 + 12i

• 13

• 13 + 12i

(3 + 8i)(-2 - i)

• 2-19i

• 23-i

• 34+5i

• 23-i
