I memorized my square roots LOL
How do you know its 24? How do you get that? Yes I have a calcualtor. They want me to use the factoring method or the extracting method.
Haha nice :)
I just need to know the process
Oh, then you'll have to go crazy and do \(\sqrt{2*288}\) \(\sqrt{2*2*144}\) .... \(\sqrt{2*2*2*2*2*2*3*3} \)
Thank you.
\[\sqrt{576}=\sqrt{2\times2\times \times2\times2\times2\times2\times3\times3\times}=\sqrt{2^6\times3^2}=2^3\times3=24\]
Then \(\sqrt{2^6*3^2}=2^3*3=24\)
or "long division" works too
What I also want to know is how to do the square root of 2,916. They literally want me to write all that out. Where do I start?!
divvy it up into parts of "2" and the algorithm is a sort of long hand division
you mean just divide by 2?
5 4 _________ /29 16 25 ---- 10,4 /416 416 answer is 54
its an alogrithm based off of x^2 + 2xy + y^2
\(\large (50+x)^2=2916\)
:( stealing my words lol @amistre, you exist twice D:
im very existential lol
what times what gives you that
i think this times that would work
That actually is the problem i dont understand. How do you find what goes into such a big number I get the general idea of how to work these it is just that though. :/
make it smaller
\(\large \begin{align} (50+x)^2&=2916 \\ 50^2 + 2*50x + x^2 &= 2916 \\ 2500+100x+x^2&=2916 \\ x^2+100x-416&=0 \\ (x+4)(x-104)&=0 \\ x &=4~or104 \end{align} \)
My method looks quite horrible to look at :S
it needs more colors
Haha xD
So you always use 50 + x as an outline?
Depends, because the nearest number squared is 50(50^2 =2500)
50*50 = 2500 60*60 = 3600 use the one thats closer to 2900
Ok. I will have to go over this. Thank you all! :D
You are welcome :)
