This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Ya, I have the complete paper, but can you give the solution to this inequality, I mean how you solved, I was trying it with Tittu's Lemma, but couldn't complete

Oh, yeah, I did it today, after I commented that. It was quite easy. Actually first I was not expanding $(a+b+c+d)^2$. I first applied Tittu's lemma and then AM-GM

Sorry. I don't know how can we upload images in comment. I think we can't upload images in comment but and upload it in solutions for given questions. Can you please write the whole solution?

Have u given the inmo mock test of fiitjee yesterday

Log in to reply

No, one of my friends gave that, and yeah, it's a question I gave from there only... Did you give that test?? How was it?

Log in to reply

Yes I gave the test and it was really difficult....this was the only question I could completely solve....I would post the complete paper soon.

$sqrt (a), sqrt (b), sqrt (c), sqrt (d) and 1,1,1,1$ it would give the direct result

Use titu lemma and then cauchy schwarz onLog in to reply

$(a+b+c+d)^2$. I first applied Tittu's lemma and then AM-GM
