Seventh power
Result of multiplying seven instances of a number
In arithmetic and algebra the seventh power of a number n is the result of multiplying seven instances of n together. So:
- n7 = n × n × n × n × n × n × n.
Seventh powers are also formed by multiplying a number by its sixth power, the square of a number by its fifth power, or the cube of a number by its fourth power.
The sequence of seventh powers of integers is:
- 0, 1, 128, 2187, 16384, 78125, 279936, 823543, 2097152, 4782969, 10000000, 19487171, 35831808, 62748517, 105413504, 170859375, 268435456, 410338673, 612220032, 893871739, 1280000000, 1801088541, 2494357888, 3404825447, 4586471424, 6103515625, 8031810176, ... (sequence A001015 in the OEIS)
In the archaic notation of Robert Recorde, the seventh power of a number was called the "second sursolid".[1]
