Question 120528
Remember {{{sqrt(25)=5}}} and {{{sqrt(36)=6}}}



So {{{5<sqrt(31)<6}}}


So I'd say it's about halfway between these values (since 31 is about halfway between 25 and 36). So I'd estimate {{{sqrt(31)}}} to be about 5.5



Note: {{{sqrt(31)=5.56776436283002}}} when I use a calculator
