Hmm I can understand but New topics are not being added  for a long time. Plzzz tell him to add some topics under the mif advanced section. The way he explains  the topic is fantastic. I also learnt calculus from his site. A really  helpful site.

#5 Re: Maths Teaching Resources » Maths Books » 2017-03-19 23:51:18

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

#6 Re: Maths Teaching Resources » Maths Books » 2017-03-19 23:04:16

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...??

How will you tell? Do you know him?

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

will be written as
. But I think that 1/√5 is more simpler than √5/5.

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

In mif, in the Trigonometry Index there are a lot of topics and every topic has 10 exercises to do. You can practice those. It really helped me too. Otherwise, there are a LOT of books available in the market for trigonometry. If you want you can buy.

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 is

In 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.

#16 Re: Maths Teaching Resources » Maths Books » 2017-03-15 22:20:15

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.

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).

What is PM...???

The most interesting thing I have found in maths till now is the amazing relationship between Fibbonacci Series, The Golden Ratio and Nature. It has really amazed me. I also find pascal's triangle very interesting. There are 7 things that leaves me awestruck about pascal's triangle.
