### Re: Maths Books

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.

The first one would respond to EM very easily but there is an even easier way.

Supposing it looked like this...

the irrationals cancel out and 5 + 5 = 10. Do you see it now?

### Re: Maths Books

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.

why see,

. Now,

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

Hi;

Can not read that Latex. The two answers they want are 2 and -2. These are the solutions of x^2 - 3 = 1

, very good! But there are 2 more answers.

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.
