Q. (−10i)+(−40+8i)=Express your answer in the form (a+bi).
Combine Like Terms: First, we need to combine like terms. The like terms are the imaginary parts (−10i and 8i) and the real parts (0 and −40, since there is no real part with −10i).(−10i)+(−40+8i)=(−10i+8i)+(−40
Simplify Imaginary Parts: Now, we simplify the imaginary parts by adding them together. −10i+8i=−2i
Combine Real and Imaginary Parts: Next, we combine the simplified imaginary part with the real part.−2i+(−40)=−40−2i
Standard Form: The expression is now in the standard form a+bi, where a is the real part and b is the coefficient of the imaginary part.So, the simplified form is −40−2i.
