Question

-i+i+1/i solve this question ​

Answer 1

Answer:

$\displaystyle \boxed{=-i}$

Step-by-step explanation:

$\Large \textnormal{First, add similar to elements from left to right.}​$

$\displaystyle -i+i=0$

$\displaystyle =\frac{1}{i}$

$\Large \textnormal{Then, rationalize.}$

$\displaystyle \frac{1*(-i)}{i(-i)}=1*(-i)=-i$

$\displaystyle i(-i)=1$

$=\frac{-i}{1}$

$\Large\textnormal{Apply Rule.}$

$\displaystyle \frac{A}{1}=A$

$\displaystyle =-i$

$\Large\boxed{=-i}$, which is our answer.
