Concept explainers
To describe:the difference between an exact value and approximation and give an example of each
Answer to Problem 42HP
The exact value of a square root represent will have infinite non repeating digits and the approximation of a square roota finite number of the digits
Explanation of Solution
Given information:
When finding square roots of numbers that are not perfect squares.
The exact value of a square root of a number is not perfect square. It will be an irrational number. Its answer will be come in decimal which represent will have infinite non repeating digits.
Example
The approximation of a square root its means rounding the numbers to a certain number of decimal digits it need a finite number of the digits, like
Example
Hence, the exact value of a square root represent will have infinite non repeating digits and the approximation of a square root a finite number of the digits.
