Question

The square root of 31 is closer to which number? 6 or 5.

Answer 1

6

Step-by-step explanation:

First, we find the squares of 5 and 6.

`\begin{gathered} 5^2=25 \\ 31-25=6 \end{gathered}`
`\begin{gathered} 6^2=36 \\ 36-31=5 \end{gathered}`

We conclude therefore that the square root of 31 is closer to 6 since it has a smaller difference.
