Question

I dont understand square roots

Answer 1

We want to find the point that best represents

`√(5)`

The square root of 5 is 2.236.

There are 4 points given on the number line:

A - 2

B - 2.1

C - 2.5

D - 3

When we approximate 2.236 to the nearest tenths, it yields 2.2

By observation, we see that 2.2 is closest to 2.1

And so, the answer is B - 2.1
