Answer: 6
Step-by-step explanation:
I guess its the students who took 0 minutes to eat breakfast.
(3 + i)^2 * (1 - 2i)^2
==============
( 1 + 2i)^2 * ( 1 - 2i)^2
Let's work on the denominator first.
((1 + 2i)(1 - 2i))^2
(1 - 4i^2)^2
(1 + 4)^2
25
now work on the numerator which does not look very nice.
((3 + i)(1 - 2i))^2
(3 - 6i + i - 2(i)^2 )^2
(3 - 6i + i + 2)^2
(5 - 5i)^2
25(1 - i)^2
25(1 - 2i + i^2)
25 (-2i)
-50i
Now put the two parts together
-50i / 25 = - 2i
There might be a shorter way to do this, but I don't know what it might be.
Answer:
It'd be -g
Step-by-step explanation:
If you were to multiply g and -1, it'd be -g since a positive time a negative is negative.
But I'm not sure if you're talking about the g in functions. I haven't learned that yet, so sorry if my answer was not what you're looking for.
