Answer for screen readers
The square root of 1296 is $36$.
Steps to Solve
- Identify the square root definition
The square root of a number $x$ is a value $y$ such that $y^2 = x$. Here, we need to find a number $y$ such that $y^2 = 1296$.
- Start estimating the square root
We can start estimating the square root by finding two perfect squares around 1296. We know that $30^2 = 900$ and $40^2 = 1600$. This means the square root of 1296 is between 30 and 40.
- Narrow down the estimation
Next, we try numbers between 30 and 40:
- $35^2 = 1225$
- $36^2 = 1296$
- $37^2 = 1369$
From this, we find that $36^2 = 1296$.
- Conclude the solution
Since we found that $36 \times 36 = 1296$, we conclude that:
$$ \sqrt{1296} = 36 $$
The square root of 1296 is $36$.
More Information
The value 1296 is a perfect square, which means its square root is an integer. Perfect squares are numbers that result from squaring an integer. The next perfect square after 1296 is 1369, which is $37^2$.
Tips
- A common mistake is incorrectly estimating between two numbers. It’s important to square the estimated numbers to check if they fall around the target number.
- Another mistake might be skipping the checking step and assuming the first guess is correct without verifying by squaring.
