The complex expression 10i / (2 – i) is equivalent to the complex expression 4i – 2. Then the correct option is C.
What is a complex number?
The complex number is the combination of the real part and the imaginary part. Then the complex number is given as
⇒ a+bi
The expression is given below.
⇒ 10i / (2 – i)
Simplify the expression, we have
⇒ [10i / (2 – i)] [(2 + i)/(2 + i)]
⇒ (20i + 10i²) / (2² – i²)
We know that i² = –1
⇒ (20i – 10) / (4 + 1)
⇒ 4i – 2
Then the correct option is C.
