Question 736996
Using a calculator is easiest way.  Making use of table of square roots maybe another way.

More laborous way,
{{{2*2=4}}}
{{{3*3=9}}}
What to square to get 6?


2.1^2=4.41
2.2^2=4.84
2.3^2=5.29
2.4^2=5.76
2.5^2=6.25
Square root of 6 is something between 2.4 and 2.5.


2.42^2=5.8564
2.44^2=5.9536
2.46^2=6.0516
Square root of 6 is between 2.44 and 2.46.


2.45^2=6.0025
Is this close enough or do you want to find something closer?
Would 2.4495 work for you?


{{{3*sqrt(6)=3*2.4495=highlight(7.35)}}}, to the nearest hundredth
