The square root of 5 is approximately 2.236 to the nearest thousandth. Rounding it to the nearest tenth would make it 2.2.
The square root of 5 is approximately 2.236. When rounded to the nearest tenth, it becomes 2.2.
Estimating square roots involves finding a value close to the actual square root but easier to work with.
In this case, √5 falls between √4 (which is 2) and √9 (which is 3), indicating it's closer to 2.2 than 2.3.
So, when approximating to the nearest tenth, 2.2 is a suitable estimation.
This rounded value simplifies calculations while maintaining a relatively close approximation to the actual square root of 5, aiding in practical applications across various mathematical contexts.
