  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

okay so remember that we can split up square roots like so:

#

if $\sqrt{ab}$ this is also $\sqrt a \times \sqrt b$

#

so if you do this in a specific way you can make one of those square roots simplify to an integer

#

So what’s the answer

sly hazel
#

oh do you want someone to just tell you answers

sly cosmos
#

Yes

sly hazel
#

well you wont find that here

#

we teach methods and provide help we are not an answer spitting machine

sly cosmos
#

Do the method and the answer so I can know

#

lets take $\sqrt{32}$ as an example

now i can write it as $\sqrt{16} \times \sqrt2$

fickle novaBOT
#

!𒐪 ɹɐupoɯ⇂ㄥ8𝟝 𒐪!

sly hazel
#

note that $\sqrt{16} = 4$

thats how you rationalize these

#

think about factors of the number that are perfect squares
