If something is "to the power of 15" then it means it is multiplied by itself 14 times (one less than 15 as the original number is already to the power of 1).
An example:
So 2 to the power of 15, which we write as 215 = 2 * 2 * 2 * 2 etc... (so we have 15 written 2's in total meaning we will make 14 multiplications) is equal to 32,768.
== A number to the second power means 'squared,' so it is 15 x 15, which is 225. == 15 to the second power is nothing but 15 squared.152 = (15 * 15) = 225. Therefore 15 to the second power is 225.225
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
0.55^15 = 0.000127479497357655364990234375
154 = 15 x 15 x 15 x 15 = 50625

15 to the negative 5th power as a fraction can also be written as 1/15 to the 5th power.
15-4/155 = 15-9 or 1/159
15 to the power of 0 = 1
5 to the power of 2 plus 15 to the power of 2 = 250
3375. (15x15x15)
1515 = 437,893,890,380,859,375
151 = 15 x 1 = 15
