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

13 + 7i

Step-by-step 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)
