Graphs o y = bx for various bases b:                      base 10,                      base e,                      base 2, an                      base 1/2. Ilk curve passes throu the pynt (0, 1) acause ony nonzero nummer raised tae the pouer o 0 is 1. At x = 1, the vailyie o y equals the base acause ony nummer raised tae the pouer o 1 is the nummer itsel.

Exponentiation is a mathematical operation, written as bn, involvin twa nummers, the base b and the exponent or pouer n. Whan n is a positive integer, exponentiation corresponds tae repeatit multiplication o the base: that is, bn is the product o multipleein n bases:
