# What is the squared root of 1444?

$38$
If you can use a calculator, of course you only have to ask it, and you'll have your answer. If you can't, you must go by trial and errors, keeping in mind that you're looking for a number whose square is $1444$.
Since it's easy to remember, or to compute, that ${30}^{2} = 900$, our number will surely be greater than $30$. Also, you don't need to check all the numbers: if a square of a number ends up with $4$, the number can end only with $2$ or $8$. So, I tried ${32}^{2}$ and ${38}^{2}$, and I found out that $38$ was the right number.
