Answer 1

The estimated root of 53 to the nearest tenth is 7.3.

Step-by-step explanation:

To find the estimated root of 53 to the nearest tenth, we need to use a calculator. When you calculate the square root of 53 the result is approximately 7.28. Since we are rounding to the nearest tenth, we need to look at the digit in the hundredth place, which is 8.

Since 8 is greater than 5 we round up to the nearest tenth giving us an estimated root of 7.3.
