Alex says all factors of 16 are even why is she wrong

Alex says all factors of 16 are even why is she wrong.
[URL='https://www.mathcelebrity.com/factoriz.php?num=16&pl=Show+Factorization']Type in factor 16[/URL] into our search engine. We get the following factor of 16:
1, 2, 4, 8, 16
[B]All of these are even [I]except[/I] 1, which is odd. This is why Alex is wrong.[/B]

Besides 8 and 1, what is one factor of 8

Besides 8 and 1, what is one factor of 8.
Using our [URL='http://www.mathcelebrity.com/factoriz.php?num=8&pl=Show+Factorization']factor calculator[/URL], or entering the shortcut [B]Factor 8[/B], we get the following factors:
1, 2, 4, 8
Excluding 1 and 8, we have [B]2, 4[/B]

Factors of 36 between 2 and 12

Factors of 36 between 2 and 12
We type in [I][URL='https://www.mathcelebrity.com/factoriz.php?num=36&pl=Show+Factorization']factors of 36[/URL][/I] into our search engine and we get:
{1, 2, 3, 4, 6, 9, 12, 18, 36}
The problem asks for factors of 36 between 2 and 12:
Between does not mean inclusive, so we have anything greater than 2 and less than 12:
[B]{3, 4, 6, 9}[/B]

Identify a pair of factors of -35 that has a sum of -2

Identify a pair of factors of -35 that has a sum of -2.
If we [URL='https://www.mathcelebrity.com/factoriz.php?num=-35&pl=Show+Factorization']type in [I]factor -35[/I] into our search engine[/URL], we see 4 factor pairs.
When we add up the factors for each pair, we see [B]7, -5[/B] added together gives us 2.

log5 = 0.699, log2 = 0.301. Use these values to evaluate log40

log5 = 0.699, log2 = 0.301. Use these values to evaluate log40.
One of the logarithmic identities is: log(ab) = log(a) + log(b). Using the numbers 2 and 5, we somehow need to get to 40.
[URL='http://www.mathcelebrity.com/factoriz.php?num=40&pl=Show+Factorization']List factors of 40[/URL].
On the link above, take a look at the bottom where it says prime factorization. We have:
40 = 2 x 2 x 2 x 5
Using our logarithmic identity, we have:
log40 = log(2 x 2 x 2 x 5)
Rewriting this using our identity, we have:
log40 = log2 + log2 + log2 + log5
log40 = 0.301 + 0.301 + 0.301 + 0.699
log40 = [B]1.602
