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 $a<\sqrt{10}<b$, 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

$1<\sqrt{10}<2 \iff 1^2<10<2^2 \iff 1<10<4$

which is false.

Option B is again false, because we would have

$2<\sqrt{10}<3 \iff 2^2<10<3^2 \iff 4<10<9$

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

Answer 2

Answer:

C

Step-by-step explanation:

√10=3.16

3.16 is between 3 and 4 hence C is the answer
