Answer: Good luck buddy
Step-by-step explanation:
Every triangle has 6 exterior angles, two at each vertex.
First, we get rid of the negative exponent in the parenthesis. We do this by moving it to the top. Our equation is now:

Next, we can cross out one n from both the top and the bottom.

Finally, we evaluate the -2
Our equation becomes:

This becomes:

This can not be simplified any further, so this is the final answer.
Answer:
The fraction of the total number of leaves did they collect altogether is 
Step-by-step explanation:
This question can be solved by a sum of fractions.
Lee collect 24/100 of the tiral number of leaves needed.
Maya collects 4/10 of the total number of leaves needed.
What fraction of the total number of leaves did they collect altogether?
This is the sum of 24/100 and 4/10.
The lesser common multiple between 100 and 10 is 100. So

We can simplify by four
The fraction of the total number of leaves did they collect altogether is
