1,6k4 is a 4-digit number.
So, 1^4 + 6^4 + k^4 + 4^4 = 16k4
Evaluate: 1 + 1296 + k^4 + 256 = 16k4
Simplify: 1553 + k^4 = 16k4
Whatever k is, it must be the case that the UNITS digit of k^4 is...

A quick solution is to say that the original 20 measurements were all 34
That is {34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34, 34}
These values definitely have an...
There's no math required for this question.
The strip can be any value, since we could choose a certain width for the strip and then just shrink or expand the inlay until the ratio of (inlay area):...
Another way to state this question is: What is the greatest common factor of 4000 and 180?
G = 10^100
We can rewrite this as follows: G = (10^3)(10^97)
Or we can say G = (1000)(10^97)
So, G/8 = (1000)(10^97)/8 = (125)(10^97)
G/5 = (1000)(10^97)/5 = (200)(10^97)
G/4 =...

You will notice that I never said that 12 people can be seated at a round table in 11! ways (Chromepal made this claim). I'm not a big fan of "people sitting at a circle" questions, because the...
When it comes to remainders, we have a nice rule that says:
If N divided by D, leaves remainder R, then the possible values of N are R, R+D, R+2D, R+3D,. . . etc.
For example, if k divided...

Let's examine the two EXTREME values of a.
Case a: The GREATEST value of a
If the values are strictly increasing (i.e., no values are equal), them a could be a little bit smaller than 8.5.
So,...
