Using the power of zero property, we find that:
a) The simplification of the given expression is 1.
b) Since , equivalent expressions are: and .
--------------------------------
The power of zero property states that any number that is not zero elevated to zero is 1, that is:
Thus, at item a, , thus the simplification is .
At item b, equivalent expressions are found elevating non-zero numbers to 0, thus and .
Answer: 
Step-by-step explanation:
We know that the area of the living room can be calculated with the formula for find the area of a rectangle. This formula is:

Where:
is the lenght of the original living room, and
is the width of the original living room.
If he creates the addition that causes the dimensions to triple, then the new area of Garrett’s living room is:

Answer:
2a - b = 5
Step-by-step explanation:
4a - 2b = 10
take out the highest common factor of the left side
2(2a - b) = 10
divide both sides by two
2a - b = 10/2
2a - b = 5
Two hundred ten thousand and fifty is written as 210,050
Nineteen-hundredths is written as 19/100 or 0.19
So, the whole number is written as 210050.19
