Answer:
Step-by-step explanation:
Hello,
Basically, we need to prove that is irrational
Let s assume that is rational
it means that we can find p and q (q different from 0) two integers <u>with no common factors other than 1 </u>
so that
And then we can write that
So is even so it means that p is even
so is divisible by 2*2=4
as it means that is even, meaning q is even
wait, p and q are then even !? but by definition they have no common factors. This is not possible.
so our assumption that is rational is false
So it means that this is irrational
and then is irrational too
Hope this helps

Answer:
C
Step-by-step explanation:
The common ratio can be < 0
All that means is the entry's signs alternate.
For example
r = - 2
a = 3
Series = 3 -6 18 -54 etc. The members of the series become larger and larger in magnitude and the series diverges. It is not clear where it might stop.
-1 < r < 0 gives a much better behaved result.
The point is that c is incorrect.
