Question

Find the difference (6+3i)-(-7-4i)

Answer 1

13 + 7i

Explanation:

We have given complex number

The difference of given complex number is:

(6 + 3i) - ( -7- 4i) = {6 - (- 7)} + {3 -( - 4)}i

⇒ 13 + 7i

Since the difference of two complex number (a + ib) and (c + id) is:

(a - c) + i(b - d)
