Answer for screen readers
The square root of 3 is approximately $1.732$.
Steps to Solve
-
Identify the Approximate Value To find the square root of 3, we first identify the approximate value between two integers. We know that $1^2 = 1$ and $2^2 = 4$. Therefore, $\sqrt{3}$ is between 1 and 2.
-
Use the Decimal Approximation Method We can estimate $\sqrt{3}$ by trying decimal values. Since $1.5^2 = 2.25$ and $1.8^2 = 3.24$, we can narrow it down further. Thus, $\sqrt{3}$ is between 1.5 and 1.8.
-
Refine the Estimation We can continue refining our approximation. Testing $1.7$, we find that $1.7^2 = 2.89$, and testing $1.73$, we find $1.73^2 = 2.9929$. Testing $1.74$, we find $1.74^2 = 3.0276$. This shows that $1.73 < \sqrt{3} < 1.74$.
-
Using a Calculator for Precision To get a more precise value, we can use a calculator. Plugging in $\sqrt{3}$ will yield approximately $1.732$.
The square root of 3 is approximately $1.732$.
More Information
The square root of 3 is an irrational number, meaning it cannot be expressed exactly as a fraction, and its decimal representation goes on forever without repeating. It is commonly encountered in various areas of mathematics, including geometry, especially in relation to the properties of equilateral triangles.
Tips
A common mistake is to assume that the square root of a number always falls neatly between two whole numbers. Additionally, some might forget that the square root can also be expressed as a decimal approximation.
