81k^2 - m^2 factors to
(9k + m)(9k - m)
Prove this by FOILing.
First - 81k^2
Outer - (-9km)
Inner - 9km
Last - (-m^2)
Put it into equation form
81k^2 - 9km + 9km - m^2
And combine terms to get the original equation,
81k^2 - m^2.

Answer:
2253 in base 6.
Step-by-step explanation:
The place values in base 6 are:
1, 6, 36, 216, 1296 and so on.
We have 537 in base 10 so we first find how many 216's there are in 537:
537 / 216 = 2 remainder 105
Now 105 / 36 = 2 remainder 33
33 / 6 = 5 remainder 3.
So the answer is 2253 in base 6.
