Exponential and Exponential
Exponential
Exponential a mathematical binary operation performed on two numbers a and b, the result of the exponentiation operation is the product of the multiplication with b factor a multiply each other. Exponential power is denoted by
, read as b power of a, the number a is called the base, the number b is called the exponent.
The operation that is the opposite of exponentiation is the root operation. Exponential (from Sino-Vietnamese: 累乘) means "to multiply". Especially
) a non-zero and n is a positive integer:
- a² also called “a squared”;
- a³ Also called "a cube".

Powers with positive integer exponents
In case b = n is a positive integer, the nth power of a is the product of n equal factors, each of which is equal to a:with everyone a ≠ 0
Powers with exponent 0
Powers to the zero exponent of the number a other is not conventionally equal to 1.Powers with negative exponents
Powers of a with a negative integer exponent m, where (.
