Can 3√2x be simplified?
I know x^2 can be simplified as x*x but is there a way to simplify 2x?

hartnn · Answer

$\sqrt{2x}=\sqrt{2}\sqrt{x}$
but i wouldn't call that a simplification :P

hartnn · Answer

so, $3\sqrt{2x}$ is in most simplified form

oh okay, just making sure. i was trying to simplify one at a time to:
3√2x + x√8x - 5√18x 
thats why i was curios lol.
but thank you!

hartnn · Answer

you need help simplifying 3√2x + x√8x - 5√18x  ?

hartnn · Answer

or you are trying first, if you need help you can ask me after u've tried...

anonymous · Answer

I tried to simplify it and got 
3√2x + 2√2x - 15√2x 
And then I got 
-15√2x
but I'm not sure if that's right or not.

hartnn · Answer

did you just change the question ? :P

hartnn · Answer

or was x√8x a typo and its just √8x

hartnn · Answer

i assume its  √8x
3√2x + 2√2x - 15√2x 
 √2x [3+2-15] = √2x [.....?...]

anonymous · Answer

oh i didnt mean to change the question! its x√8x

hartnn · Answer

:O 
then, we have 
3√2x + 2x√2x - 15√2x 
 √2x [3+2x-15] = √2x [.....?...]

anonymous · Answer

√2x - 12 ? Would that go before the radical?

hartnn · Answer

how you got √2x - 12 ?
3+2x-15 = 2x-12
so, 
√2x [3+2x-15] = √2x [2x-12]
thats it!

anonymous · Answer

oh okay, i just thought because it was after the radical. thank you!
