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}
