ledah · Answer

$$\sqrt{144x}+\sqrt{36x}-\sqrt{25x}$$

diyadiya · Answer

First of all$$\sqrt{144}=12$$$$\sqrt{36}=6$$$$\sqrt{25}=5$$

ledah · Answer

Wow.. I feel stupid I COMPLETELY over looked that.

diyadiya · Answer

$$12\sqrt{x}+6\sqrt{x}-5\sqrt{x}$$

diyadiya · Answer

Can you do the rest?

anonymous · Answer

you can use $$\sqrt{ab}=\sqrt{a}*\sqrt{b}$$
for example $$\sqrt{144x}=\sqrt{144}*\sqrt{x}=12*\sqrt{x} $$

anonymous · Answer

sorry ,Diaadiya I didn't see your post; I'll delete mine!

ledah · Answer

Could I square the radicals to get rid of them?

diyadiya · Answer

@Neemo Its not a problem :)

diyadiya · Answer

No you can't @Ledah

ledah · Answer

ah okay then.

diyadiya · Answer

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 

$$\sqrt{144x}=\sqrt{25}$$

diyadiya · Answer

So what did you get as your final answer?

ledah · 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.

diyadiya · Answer

Yes! you're Right :) so what did you get ?

ledah · Answer

13 is what I ended up with.

diyadiya · Answer

You're right! don't forget the $\sqrt{x}$

ledah · Answer

Oh okay  oopsie. 
Thank you :D
