The exponent of a number says how many times to use the number in a multiplication. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared". Exponents make it easier to write and use many multiplications. Example: 96 is easier to write and read than 9 × 9 × 9 × 9 × 9 × 9.
An exponent symbol is a number or sign placed after and above some other number and symbol. The exponent symbol is also known as the power symbol because it is the power of the digit or number above it. For example, b x means that x is the power of base “b”.
In mathematics, exponentiation is an operation involving two numbers: the base and the exponent or power. Exponentiation is written as bn, where b is the base and n is the power; often said as " b to the power n ". [1] .
Basic rules for exponentiation. If n is a positive integer and x is any real number, then xn corresponds to repeated multiplication. xn = x × x × ⋯ × x n times. We can call this “ x raised to the power of n,” “ x to the power of n,” or simply “ x to the n.” Here, x is the base and n is the exponent or the power.
Laws of Exponents. Exponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the second power", "8 to the power 2" or simply "8 squared". Try it yourself:
