Answer:

Step-by-step explanation:
Given:
The expression to simplify is given as:

In order to simplify this, we have to use the law of indices.
1. 
So, 
Substitute this value in the above expression. This gives,

Now, we use another law of indices.
2. 
So, 
Substitute these values in the above expression. This gives,

Finally, we further simplify it using the law 
So, 
Therefore, the given expression is simplified as:

Each person can eat 2 ears of corn because 32/15=2.13333333. So there will be 2 ears of corn left over!!
Yea but it would be an obtuse triangle
If you are rounding it will be the same thing
No it far 10 is way out there
