Question

80=75 + i(0.04)
how to calculate without calculator? ​

Answer 1

Step-by-step explanation:

i (4/100)+75=80

i (4/100) =80-75

i=5×25/1

i=125

Answer 2

80 = 75 +i(0.04)

On comparing ,

The coefficient of imaginary part = 0 on LHS

--> 75 = 80 ( WHICH IS IMPOSSIBLE )

I guess your question must be incomplete.
