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?

Hi;

That is not what I mean. Look at it this way.

has an exponent of 2.

has an exponent of 3.

has an exponent of?

True enough but the simple things are the secret to it all.

Do you follow this?

Supposing it looked like this...

the irrationals cancel out and 5 + 5 = 10.

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.

Yes, I know. I left that for you.

Math types love these types of questions and that is the whole problem!

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

Do not worry about it. You are correct about the

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.

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.
