Understanding Square Roots
In mathematics, a square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16. Square roots are denoted by the symbol . In this article, we will explore the concept of simplifying square roots and evaluate the expressions equivalent to .
Simplifying
To simplify , we need to find the largest perfect square that divides 200. A perfect square is a number that can be expressed as the product of an integer with itself. For example, 16 is a perfect square because it can be expressed as 4 multiplied by 4.
The prime factorization of 200 is . We can rewrite as . Since is a perfect square, we can simplify it as . Therefore, can be rewritten as .
Simplifying Further
We can simplify by breaking it down into two separate square roots: and . Since is not a perfect square, we cannot simplify it further. However, can be simplified as , because 5 multiplied by 5 equals 25.
Therefore, can be simplified as . We can further simplify as , which equals .
Evaluating the Expressions
Now that we have simplified as , we can evaluate the expressions given in the options.
Option A:
To evaluate this expression, we need to simplify . The prime factorization of 8 is . We can rewrite as , which equals .
