Answer:
To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.
Coefficients are added together because they are like terms, this can be proven with the distributive property. For example, x(2x+x)=2x^2+x^2=3x^2.
The commutative property of addition and the associative property demonstrate this.
The word "commutative" comes from "commute" or "move around", so the Commutative Property<span> is the one that refers to moving values around.

The associative property<span> states that you can add or multiply regardless of how the numbers are grouped. </span>

Hello!</h2>
The answer is:
The correct option is:
C) 
<h2>
Why?</h2>
To solve the problem, we need to remember the product of powers with the same base property, the property is defined by the following relation:

If we are multiplying two or more powers with the same base, we must keep the base and add/subtract the exponents.
So, we are given the expression:

We can see that both powers have the same base (4), so solving we have:

Hence, we have that the correct option is:
C) 
Have a nice day!
For this case we have the following conversion of units:
Therefore, we must apply this conversion for the apartment area.
We have then:
Answer:
The area of the apartment in square meters is given by:
