How do you work out the square roots? I mean for instance how do you work out 3 square root 8... I done 8x8x8 and 3x3x3x3x3x3x3x3 but both give out different answers LOL I don't know how you work out square roots!!!!!!!!!!!! Plz help y'all
+118724 $$3\sqrt8 = 3*\sqrt{4*2} = 3*\sqrt4*\sqrt2=3*2*\sqrt2=6\sqrt2$$
I have simplified it. You can do it on the calc but that will give you an approcimation.
Oh when i wanted to simplify $$\sqrt8$$ i looked for a square number that would go into 8. I found 4.
If there was no square number that went inot 8 then I would not have been able to simplify it :)
+7188 Square root is one number, multiplied by itself, equals another number
Like
9*9=81
The square root of 81 is 9
To calculate the square root of 8 you use the square root button labelled $$\textcolor[rgb]{0,0,1}{\mathbf{\sqrt x}}$$
Too easy! 
There are ways to work it out if you don't have a calculator. One of those ways resembles a wierd long-division procedure, but you would probably think it looks too complicated.
