Answer: 
The expanded form of the number 0.0001 is
.
<u>SOLUTION:
</u>
Given that, we have to write 0.0001 in expanded form.
Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression.
Now, take the given number 0.0001
As there are no other digits except 0 in front of 1 our work is simplified.
Expanded form will be 
Hence, the expanded form of the number 0.0001 is
.
