Question

(1-6i)-(3-4i)
please solve this perblom

Answer 1

-2 - 2i

Explanation:

open the bracket

1 - 6i - 3 + 4i

1 - 3 + 4i - 6i

-2 - 2i

Answer 2

-2 - 2i

Explanation:

Complex number

Add the real numbers (1 and (-3) ) and add the complex numbers [ 4i and (-6i) ]

(1 - 6i) - ( 3 - 4i) = 1 - 6i - 3 + 4i

= 1 -3 - 6i + 4i

= -2 - 2i

• We have to open the brackets. To do that Multiply (-1) with (-3) & 4i.
• Now, complex numbers are (-6i) and 4i. So combine them. 6i and 4i have different signs. So, subtract and the result will have bigger number sign. Here the bigger number sign is negative. So, -6i + 4 i = -2i
• Now combine real numbers. 1 - 3 = -2
