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:

9.) 3
10.) 1
11.) x-axis
12.) 4
13.) y-axis
