Explanation:
When you see some term raised to a negative power, it's really shorthand for division.
In other words,
So
Notice that the
At this point, we notice that
And
Note: It is also appropriate to mention that
Explanation:
First, let's rewrite this without the negative exponent. The negative means that the term is in the denominator:
Now, let's distribute the power in the denominator:
The last step is to cancel out the
We can do this because any number divided by itself is 1 which means:
We can also approach the original problem a different way.
After we distribute the
Now when we simplify this equation we get:
After rearranging this expression we can then use the rules of exponents. When you multiply terms with the same base you add their exponents together:
