The exponential expression a^n is read a to the nth power. In this expression, a is the base and n is the exponent. The number represented by a^n is called the nth power of a.
When n is a positive integer, you can interpret a^n as a^n = a x a x ... x a (n factors).

base
Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base. For example, in 23 two is the base.
You can choose the base to be any number (other than 0, -1 and 1) and calculate the appropriate exponent, or you can choose any exponent and calculate the appropriate base. For example, base 10: 121 = 10^2.08278537 (approx) Or exponent = 10: 121 = 1.615394266^10 (approx). I expect, though, that the answer that is required is 121 = 11^2.

Base and exponent are the two parts of a power. The base is the lower left, normal-sized, number. The exponent is the upper-right, small (i.e., superscript) number. For example, in: 34 3 is the base, 4 is the exponent. In the simplest case, a power specifies a repeated multiplication. The base tells you what number to multiply by itself, the exponent tells you how many times to multiply it. Thus, 34 = 3 x 3 x 3 x 3 (that is, multiply 3 by itself, using the number 4 times as a factor)
