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.
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 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.
oh, that means moderators and real members and administrators get a private message facility? How is it can anyone explain it to me...
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...???
Yeah I know it.
This is one of the 7 things of the pascals triangle which i find very interesting.
Hey, I want to ask something. Below or above all topics; at your left hand side there is a link "Subscribe to this topic". When we click on it is written "Subscribed" and then if we click on "Unsubscribe" the message is unsubscribed. What is it?
hey, what message did john21wall sent?? Why was it a spam?? What did he do????? Plzz tell me.
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.
How did he do that with only 15 posts?
What do you mean to say??
Yes they are 3 different questions. And please not that i had given the last question wrong. I have edited it. Please see.
And yeah you have to simplify the following.
Maybe more than 1000 posts! After 1000 posts you automatically become a super member! But strictly no spamming is permitted! Let it take its time, you would be a real member!
In User list many people have thousand and more than that no. of posts still many of them are still "members". On the other hand many of them has less than thousand and hundred and very less posts and still they are moderators or real members. Administrators are only two bobbym and mathsisfun. It seems that mif promotes those persons who are for very long time registered. The most recent registered user who is promoted to a moderator or real member(according to user list) has registered in the year 2011. Still many old users do not have been promoted. I am also in a confusion for a struct rule or getting promoted by mif. Bob bundy had already explained me that due to some hackers who joined ago many trusted users where getting promoted to remove them. But...does that mean that no one will get promoted until another group of hackers join... Plz may i get this reply from Mathsisfun.
Hi HannahBanana,
I do not know whether you know how to solve linear equations or not;yes it seems like your school homework and if you don't know then I would recommend you to first read Solving Equationsin Maths is fun(and you may practice the exercises in there as well) and then try to solve the questions yourself.
how do you become a supermember or realmember because my rank is novice and i cant change it i am fairly new here please help me is there somthing i have to do javascript:insert_text(':|',%20'');
You are a real member. However, if you have doubt you can visit a post by bob in Hello #11
for more details
I have to press "New" to see a new post or I use refresh too. This is not a chat.
Ok
