The powers 2 and 3 are the base-10 logarithms of 100 and 1000. Expressed mathematically x is the logarithm of n to the base b if bx n in which case one writes x log b n. Or log base 2 of 8 is 3.
There are various cases.
So these two things are the same. If you arent familiar with calculus dont worry. The powers 2 and 3 are the base-10 logarithms of 100 and 1000. Because log is a static method of Math you always use it as Mathlog rather than as a method of a Math object you created Math is not a constructor.
