Show that, if n is an integer and n^3 + 5 is odd, then n is even, using:

Ilya [14]

Answer:

Explanation:

Let n be an integer

Given that $n^3+5$ is odd

To prove that n is even

a) Proof by contraposition

Let $n^3+5$ be non odd

Then this would be a multiple of 2 being even

$n^3+5 = 2m\\n^3=2m-5\\n^3=2(m-3)+1$

i.e. we get cube of n is odd since gives remainder 1 when divided by 2

It follows that n is odd.

Thus proved by contraposition

b) contradiction method:

If possible let $n^3+5$ is odd for n odd.

Then we get

since n is odd,

$n^3$ is odd being the product of three odd numbers

When we add 5, we get

$n^3+5$ is even being the sum of two odd numbers

A contradiction

Hence our assumption was wrong

if n is an integer and n^3 + 5 is odd, then n is even

It is true, because if you would try installing another OS after installing the first one, you would overwrite the OS which you installed before.
but in the second opinion an workstation is technically able to dual boot by installing differend operating systems on different drives. which approves that both answers can be right.
