1. (2×100,000)=200,000

2. (7×10,000)=70,000

3. (9×100)=900

4. (5×10)=50

200,000+70,000+900+50=270,950

Answer:

Step-by-step explanation:

first multiply 1 with 2+5i then multiply 2i with 2+5i and you will get

2+5i+4i+10i^2

then in the next step add 4i and 5i you will get 9i

in the next step put i^2=-1 and you will get -10

in the last step just substract 2-10 you will get -8 and 9i
