Numbers are classified as:
- Whole, which is all positive numbers and zero, also called natural.
- Integers, which is the set of whole numbers plus negatives.
- Rational, which is the set of integer numbers plus terminating or repeating decimals.
- Irrational, which are non terminating decimals.
- Real, which are the sum of rational and irrational.
In this problem, the number given is:

- Which is a whole(natural) number, thus it is also integer, rational and real, and the correct option is C.

Answer:
n² p²r³
Step-by-step explanation:
n ⋅ n ⋅ p ⋅ p ⋅ r ⋅ r ⋅ r
Write using exponents
There are 2 n terms
n²⋅ p ⋅ p ⋅ r ⋅ r ⋅ r
There are 2 p terms
n² p²⋅ r ⋅ r ⋅ r
There are 3 r terms
n² p²r³
Alright, so we have the difference = 4500-2800=1700. To find the percent increase, we do 1700/2800=around 0.61 = around 61% percent
