Is 3.14 a Rational, Whole Number, Integer, or Irrational number?
2 answers:
Answer:
It is a rational number.
Step-by-step explanation:
A rational number means it can be expressed in the form
which it clearly can, as 3.14 as a fraction results in
A whole number and an integer mean the same; a number without decimals or fraction. Clearly 3.14 is not a whole number and not an integer as it has decimals.
An irrational number is the opposite of the said above rational number; it cannot be expressed as a fraction.
Hence, 3.14 is a rational number.

Answer:
See explanation below
Step-by-step explanation:
<u>First we will solve the radical equation</u> (which I guess was problem 1),
Let's start by simplifying it:
Now we will solve the equation by squaring both sides of the equation:
So the calculation for x was that x = -10
However, this does not produce a solution to the equation: When we plug this value into the radical equation we get:
This happens because <u>when we first squared both sides of the equation in the first part of the problem we missed one value for x </u>(remember that all roots have 2 answers, a positive one and a negative one) while squares are always positive.
When we squared the root, we missed one value for x and that is why the calculation does not produce a solution to the equation.
