11
Answer for screen readers
The final answer is 11
Steps to Solve
- Recognize the square root operation
The square root of a number is a value that, when multiplied by itself, gives the original number. So, we need a number $ x $ such that $ x imes x = 121 $.
- Find the number
Identify the number that satisfies the equation $ x^2 = 121 $: $$ x = ext{the square root of } 121 = ext{?} $$ We know that $ 11 imes 11 = 121 $, so: $$ \sqrt{121} = 11 $$
- Verify the result
Double-check by squaring the result to ensure it gives 121: $$ 11 imes 11 = 121 $$
The final answer is 11
More Information
The square root of a number can be found by identifying the value that, when multiplied by itself, yields the original number. For example, the square root of 121 is 11 since 11 times 11 equals 121.
Tips
A common mistake is incorrectly identifying the square root. Make sure to verify by multiplying the result back to get the original number.
