Answer 2

Answer:

7.07

Step-by-step explanation:

Hello!

Let's find two perfect square numbers that are directly before and after 50.

• $\sqrt{49} < \sqrt{50} < \sqrt{64}$
• $7 < \sqrt{50} < 8$

Since the square of 7 is the closest, we can use that as our whole number.

To find the decimal...

49 is 1 away from 50, and 64 is 14 away. Rewriting it as a fraction and we get  $\frac{1}{14}$.  The decimal is 0.07142857142.

Now, put 7 and 0.07142857142 together and we get 7.07142857142. Rounding that, we get 7.07.

The real value of Root 50 is 7.071067811865475, so the decimals were really close.
