**Exponents**

We can write large numbers in a short form using exponents.

For example: 125 = 5 x 5 x 5 = 5^{3}

Here, ‘5’ is called the base and ‘3’ the exponent. The number 5^{3} is read as 5 raised to the power of 3.

**Decimal Number System**

10,000 = 10^{4}

1000 = 10^{3}

100 = 10^{2}

10 = 10^{1}

1 = 10^{0}
