We know how to calculate the expression 5 x 5. This expression can be written in a shorter way using something called exponents.

5 \times 5 = 5^{2}

An expression that represents repeated multiplication of the same factor is called a power. In the number 5^{2}

The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.

Example

Have a look at these multiplications written as exponents

2 \times 2 \times 2 = 2^{3}

4\times 4\times 4\times 4 = 4^{4}

5 \times 5\times 5\times 5 \times 5 = 5^{5}
