Here are a few rules you need to know for this equation:
- Multiplying exponents of the same base:
- Dividing exponents of the same base:
- Turning a negative exponent to a positive one:
So this is our algebraic expression:
Firstly, multiply 3^-4 and 3^2:
Next, divide:
Next, turn the negative exponent into a positive one:
<u>Your final answer is 3/2, or 1.5.</u>
First, let's get the perimeter of the rectangle:
Then, let's get the area of the bigger one:
Then let's try using a rectangle with a smaller ratio:
Then:
If you used a square:
There you have it. A rectangle with a smaller area with the same perimeter.
What does it show? The smaller the difference you get from width and length, the larger the area is.
