Off coloured advertisement means???

He doesn't appear so much in the forum nowadays. Do you know why?

No, I found it out myself. Why is it wrong?

Hmm, yours solution is right but actually I a

Had found a different solution. It is

Thus we can take y as 2 and z as 1

Where did you get x as 1.609608190...??

Are you talking about the user MathsisFun in this forum?

How? What is his real name?

I am glad that MIF helped you. I will tell MIF about that.

How will you tell? Do you know him?

You are welcome

Hi;

your 1st answer is now correct. Yes you told right that we always rationalize the denominator... but still 1/√5 is more simpler... we rationalize the denominator when we have a fraction whose numerator or denominator is composed of more than 1 term. Example

Your 2nd answer(answer of the 4th question) is wrong. Take x as 1 and then see it would not be matching.

Welcome to the forum.

1. Rewrite each expression in simpler form using exponents: (6x)(6x)(6x)(6x)

Do, you know what exponents are. Exponents or power of a number is the no. of times the no. is multiplied (by itself). For more explained information Exponents Section in mif.

So, since here

is multiplied 4 times it isIn The 2nd question just expand it into the multiplication form( as bobbym had done) and then reduce it.

The 3rd question will also be the same...

Hope it helps.

No; only in the 1st question; for the rest questions you have to simplify them, understood.

Your 1 st answer is correct but you need to simplify the fraction.

Hi;

Have you seen the post? Long time no reply. Are you not able to solve these problems... If you want I may tell you the solutions... I am waiting for your reply and then will send you the difficult problems of other questions also... If you want I may send you the problems of other questions also. Please reply.

The only trouble with chat is that we can't monitor conversations with younger members (a duty of care).

I can upgrade you to Real Member so you can PM (not really the same, but still helpful).
