Question

Simplify:
3√5 + √5

Option A: 3√5
Option B: 4√5
Option C: 4√10
Option D: 3√10

Answer 1

Treat sqrt(5) as you would a variable x.
What's
3x + x
?

Answer 2

There I added the options to choose from.

And if I go by what your saying, then x =5.

3(5) + 5 = 20.

20 is not an option. Plus, I'm not wanting to solve it. It says to Simplify.

Answer 3

I did not say x = 5
I said x = sqrt (5)
You know... square root of 5?

Answer 4

Right so 3(2.236) + 2.236 = 8.944.

So, 8.9? It still doesn't help me. Either you aren't getting the question, or I'm not understanding you. And, again, simplify.

Answer 5

Why put in 2.236?
That's not even equal to the square root of 5, exactly.
Also, I told you to solve
3x + x
That's just 4x.
And then replace x with sqrt(x).

Answer 6

*sqrt(5)
sorry.

Answer 7

Right so I'm getting nowhere. Forget it. I'll do research online, hope for somebody else to respond.

Answer 8

/sigh/
\[\huge 3x + x = 4x\]\[\huge 3\sqrt5 + \sqrt5 = 4\sqrt5\]

Answer 9

Right. Thank you so much, genius. Thank you for sighing and giving me the answer rather than explaining it clearer.

Worst experience on this website so far. Gratz'.

Answer 10

I did tell you how to go about it, I said to treat the radical square root of 5 as you would a variable, x.
Oh well...
Try not to be so rude, next time.

Answer 11

Try not to be such a smartass next time then. Treating me like I'm an idiot or something instead of explaining it further.

Bye.

Answer 12

Good luck with your studies.

Answer 13

Yeah. Thanks for your 11/10 assistance bud.
