Which point on the number line best represents√57?

Cerrena [4.2K]

Answer:

Step-by-step explanation:

$\sqrt{57} =\sqrt{3 * 19}$

Since this cannot be further simplified, we will calculate the square root of 57 with our calculators.

We find that the square root of 57 is 7.549834435, and since the tenths place is a 5, we will round up to the next whole number. So, the point on the number line that best represents the square root of 57 is 8.
