The answer is: 
The explanation of this exercise is shown below:
1. You have the following expression given in the problem above:
2. By the exponents properties, when you multiply powers with the same base, you must sum the exponents. In this case the base is 
, therefore, you must sum the exponents.
3. The result of the sum is 6, therefore, 
must be 4:

Answer:
<h2>The answer is option A</h2>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius of the circle
From the question
r = 15.2 cm
The area of the circle is
A = (15.2)²π
= 231.04π
= 725.833566685386...
We have the final answer as
<h3>725.8 cm²</h3>
Hope this helps you
Answer:
6b^2 +4b
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
A = 1/2 * (3b+2) * (4b)
=1/2 (12 b^2 +8b)
= 6b^2 +4b
