Answer:
Step-by-step explanation:
I think it is 3200 because you divide 8000 by 5 then multiply that by 2
Answer:
it is 31/20 but in mixed form it's
Remember that (a-b)(a+b)=a²-b²
and (imaginary number)²=real
so if we have a+bi, then a-bi is the conguate because (a+bi)(a-bi)=a²+b²
if the complex number is a+bi the conjucate is a-bi
