Answer for screen readers
Yes, the square root of 25 results in a whole number, which is 5.
Steps to Solve
- Calculate the square root of 25
To find out if the square root of 25 is a whole number, we first calculate it. The square root of a number $x$ is a value $y$ such that $y^2 = x$. For our case:
$$ \sqrt{25} $$
- Determine the result
Now, let's calculate the value:
$$ \sqrt{25} = 5 $$
This means that $5^2 = 25$.
- Check if the result is a whole number
Since $5$ is a whole number, we can conclude that the square root of 25 is indeed an integer.
Yes, the square root of 25 results in a whole number, which is 5.
More Information
The square root of a perfect square (like 25) is always a whole number. In this case, 25 is a perfect square because it can be expressed as $5 \times 5$.
Tips
Common mistakes include:
- Confusing square roots with other operations, such as squares.
- Forgetting that both positive and negative numbers can produce the same square when squared (though in this case we only consider the principal square root for whole numbers).
