Exponent division positive by positive to negative
Test your understanding of exponent division positive by positive to negative by practicing it! Work through the below exercises to use it in practice.
🎙️
What is 'R' to the power of 3, divided by 'R' to the power of 5?
🎙️
Let's first expand the exponents
🎙️
Now we can cancel matching terms on top and bottom
🎙️
We are left with two R's, or 'R' squared on the bottom
🎙️
1 over 'R' squared is the same as 'R' to the minus 2
🎙️
As a simple rule, dividing exponents results in subtracting their powers
