Question

What’s the correct answer for this?

Answer 1

The square root of 10 is a number with the following property: when you square it, you get 10.

So, if we have
`a<√(10)<b`, where
`a` and
`b` are positive integers, if we square the whole inequality we have

`a^2<10<b^2`

Let's analyse option A for example. Given everything we said so far, we would have

`1<√(10)<2 \iff 1^2<10<2^2 \iff 1<10<4`

which is false.

Option B is again false, because we would have

`2<√(10)<3 \iff 2^2<10<3^2 \iff 4<10<9`

which is again false. Keep trying with options C and D following those same steps, and see which one is correct

Answer 2

C

Explanation:

√10=3.16

3.16 is between 3 and 4 hence C is the answer
