Answer:
1. 
2. 7
3. 18
Step-by-step explanation:
Question 1:
Given:
The expression to simplify is
.
We use the property of exponent 
Therefore, 
Question 2:
Given:
The expression to simplify is
.
We add the fractions first inside the parenthesis.
So, 
Now, 
Question 3:
The first five prime numbers are 1, 2, 3, 5, and 7.
Therefore, the sum of these five numbers is given as:

Answer:
x^2 - (4+13i)^2
Step-by-step explanation:
This product has the form (a-b)(a+b), which is a 'special product' equal to a^2 - b^2. Following this pattern, [x-(4+13i)][x-(4+13i)] = x^2 - (4+13i)^2. The 2nd term could be expanded if desired, but the above result is the most compact one possible.
