And yeah, one thing I don't understand in this forum is that when you are sending the message, I am not receiving it, I have to refresh the page or go back to the previous page to again receive your message. Is this a similar problem happening with you all. If yes then how can I resolve it because then we will constantly have to go back and see whether you have sent a message or not for 2 persons marked "online" chatting in this forum.

#352 Re: Maths Teaching Resources » Maths Books » 2017-03-08 23:35:54

Hmmm, yeah you are absolutely correct.

Ok, now solve the other 2 problems. I will send you the other questions of other chapters later when i will get time because now I have to go to play and then study. Ok bye had a nice online chat with you.

, very good! But there are 2 more answers.

There are infinitely many non-trivial solutions.

M, agrees with you. There are only 4 Real solutions and I suppose that will be enough for his purposes.

Yes, as you wrote -2 can also be correct. You have written there are 4 real solutions and i have till now got 2,-2&√2. What is the other one.
P.S.- Sorry for not following ; my net is constantly getting cut; why I dont know.

ii am extremely sorry , I went offline ,actually my net connection lost and now it returned again

#355 Re: Maths Teaching Resources » Maths Books » 2017-03-08 22:55:20

I am exxxxxxtremely sorry for being offline; my connection suddenly broke down.

why see,

. Now,

Now, thus on the other term it will be
and then the irrationals will cancel out leaving 5+5=10

#358 Re: Maths Teaching Resources » Maths Books » 2017-03-08 22:23:55

Oh oh now I finally understood; we see here that when the power of expression

power is
then the irrationals cancel out and we are left with 10. so we equate
and get the result as
so 2 is our answer. But see carefully not only 2 but another value can be our answer.

Oh it is 1. Is this a question??? Even a child can answer that.

oh oh oh oh now i understood what you mean to say. It is

No, did not understand... i am getting

#364 Re: Maths Teaching Resources » Maths Books » 2017-03-08 21:38:59

How did you do the 1st one. It seems to be a great problem for me till now. I have not figured out the solution till now.

#365 Re: Maths Teaching Resources » Maths Books » 2017-03-08 20:38:09

These are some of the questions in chapter surds. There are around ten more. Then there are other chapters. I am going to eat now... I will post you the other  questions later.

#366 Re: Maths Teaching Resources » Maths Books » 2017-03-08 20:24:15

Now i am posting you the difficult questions

#368 Re: Maths Teaching Resources » Maths Books » 2017-03-08 20:21:45

Oh oh oh we have to use a backslash for for the functions to work. Now:

\frac{5}{2}

will give

\sqrt{x^2+y^2}

will give

4\pi r^2

will give

Let me test it first since i am using it for the first time.

Sorry, I don't understand your question.

Root over means a sign of root extended for an operation of various terms or variables or constants. It means the root of the value of the whole operation. For example root over of s(s-a)(s-b)(s-c) where the root is for the whole value of that function. You have only shown me how to write √2 or for a single variable or constant. So i was asking for the root over.

Hi iamaditya;
Remember codecogs!

Yes, but i did not understand it; I find  much easier to learn from the sticky post by dross on Latex. Now, i have learnt it and i will be posting you the questions.

#373 Re: Maths Teaching Resources » Maths Books » 2017-03-07 21:25:44

How can I print the sign of Square root. If you tell me this much it will be done.

#375 Re: Maths Teaching Resources » Maths Books » 2017-03-06 20:54:30

Hi, boobym the questions are there but it will be well understood to u if i use the Latex format but actually i have not learnt it yet and it will be extremely confusing to u if i write with the common symbols in keyboard such as "/"to denote fractions and "^" to denote exponent so i will learn the Latex format and then give you the questons
