Powerful Patterns 2: The Negative Powers of 5
There are many numerical patterns to find in mathematics! The one on this Web page is about the negative powers of 5.
Observe the negative powers of 5 in decimals below:
5-1 = 0.2
5-2 = 0.04
5-3 = 0.008
5-4 = 0.0016
5-5 = 0.00032
5-6 = 0.000064
5-7 = 0.0000128
There's a function for this pattern & have you noticed that each decimal is a power of 2 divided by a power of 10?
5-n = 2n/10n
Speaking of patterns, maybe you already seen some other numerical math patterns that other mathematicians already discovered & published! (Besides me or you; any open-minded person can be a great mathematician, like me!)
