From place value of numbers,
we know that
Thousands |
Hundreds |
Tens |
Ones |
2 | 4 | 8 | 6 |
We write the number as
2486 = 2 × 1000 + 4 × 100 + 8 × 10 + 6 × 1
= 2 × 10 ^{ 3 } + 4 ×10 ^{ 2 } + 8 × 10 ^{ 1 } + 6 × 10 ^{ 0 }
So, we can write any number as power of 10
For number,

We write the number as
98276 = 9 × 10,000 + 8 × 1,000 + 2 × 100 + 7 × 10 + 6 × 1
= 9 × 10 ^{ 4 } + 8 × 10 ^{ 3 } + 2 × 10 ^{ 2 } + 7 × 10 ^{ 1 } + 6 × 10 ^{ 0 }
For number,
Tens |
Ones |
2 | 8 |
We write the number as
28 = 2 × 10 + 8 × 1
= 2 × 10 ^{ 1 } + 8 × 10 ^{ 0 }
For decimal number,
849.58
In place value table

So, we write the number as
849.58 = 8 × 100 + 4 × 10 + 9 × 1 + 5 × 1/10 + 8 × 1/100
= 8 × 10 ^{ 2 } + 4 × 10 ^{ 1 } + 9 × 10 ^{ 0 } + 5 × 1/10 ^{ 1 } + 8 × 1/10 ^{ 2 }
= 8 × 10 ^{ 2 } + 4 × 10 ^{ 1 } + 9 × 10 ^{ 0 } + 5 × 10 ^{ -1 } + 8 × 10 ^{ -2 }
