Simplify (posting via equation editor)
\[\sqrt{144x}+\sqrt{36x}-\sqrt{25x}\]
First of all\[\sqrt{144}=12\]\[\sqrt{36}=6\]\[\sqrt{25}=5\]
Wow.. I feel stupid I COMPLETELY over looked that.
\[12\sqrt{x}+6\sqrt{x}-5\sqrt{x}\]
Can you do the rest?
you can use \[\sqrt{ab}=\sqrt{a}*\sqrt{b}\] for example \[\sqrt{144x}=\sqrt{144}*\sqrt{x}=12*\sqrt{x} \]
sorry ,Diaadiya I didn't see your post; I'll delete mine!
Could I square the radicals to get rid of them?
@Neemo Its not a problem :)
No you can't @Ledah
ah okay then.
Since ,your question is to simplify it and you just can't square it if it was an equation like this, you could square both sides \[\sqrt{144x}=\sqrt{25}\]
So what did you get as your final answer?
not sure that I did this right. that's why I'm asking :c I ended up adding the 12sqrt{x}+6sqrt{x} then subtracting the last one from it.
Yes! you're Right :) so what did you get ?
13 is what I ended up with.
You're right! don't forget the \(\sqrt{x}\)
Oh okay oopsie. Thank you :D
You're Welcome :)
