luigi.colarullo47:
radice quadrata di 144

Hi Luigi,
I was just thinking this morning that it has been a while since i answered non-English questions.
You are very welcome here.
I hope the translator works well and this all makes sense.

square root of 144
Alright, let's see.
-----------------------------------------------------------------------
5 squared is written as 5 ² and it means 5 x 5 and it equals 25
Now square root is the opposite of square.
The square root of 25 is 5 because 5 x 5 = 25

the square root of 100 is 10 because 10 x 10 = 100
So do you know what the square root of 144 is now?

Translated back into Italian
------------------------------------------------------------------------------------------------------------------------
Ciao Luigi,
Stavo pensando questa mattina che è stato un po 'che ho risposto alle domande non inglesi.
Siete i benvenuti qui.
Spero che il traduttore funziona bene e questo rende ogni senso.

radice quadrata di 144
Va bene, vediamo.
-------------------------------------------------- ---------------------
5 squadrato è scritto come 5 ² e significa 5 x 5 ed è uguale a 25
Ora radice quadrata è l'opposto della piazza.
La radice quadrata di 25 è 5 perché 5 x 5 = 25

la radice quadrata di 100 è 10 perché 10 x 10 = 100
Allora sapete che cosa la radice quadrata di 144 è ora?

Guest:
what is the average unit of sale. serves 2100 in meals to 115 customers

Hi Guest,
I think that you are being asked what is the average number of meals per cusomers.
-----------------------------------------------------------
I just want to talk about non-related things first.
now three people get these marks in a test 4, 7, and 2
Then the average mark is the total of all the marks divided by how many marks there were. That is (4+7+2)/3
------------------------------------------------------------

Now in your question you have already got the total number of meals, that was already added for you.
And you have got the number of customers.
So can you work out the average number of meals per cusomer by yourself now?

woods:
(t-4)^4

Hi Woods,
When you write questions like this please use the 'sup' that is located above the smilies
to type this just type
(t-3) then hit the 'sup'button, your curser will be put in the correct position to type 4 then just move the curser to the end and you are done.

(t-4) ⁴
---------------------------------------------------------------------------------------------------------------------------
Now, there are different ways to do this. If you are a senior student then you are probably supposed to do this with a binomial expansion.

http://www.mathsisfun.com/algebra/binomial-theorem.html

I think that it would be a good idea for you to work through this web page.

When you do your one,
a will be replaced by t and b=-4
------------------------------------------------------------------------------------------------------------------------------
If you are a younger student and you have no idea what i am talking about you can do it the long way.
that is
(t-4)(t-4) = work that out and it will = t ² - 8t + 16
so
(t-4) ⁴ = ((t-4)(t-4) X (t-4)(t-4) = (t ² - 8t + 16)(t ² - 8t + 16) => you work it out

You are welcome to reply if you want more help. If you do, tell me something of what you have done, or what you are stuck on.

Another week is finished. Sat for me but Friday for most of you i think.
We had some great answers today from Rom, I like Serena and Selina Marie. Thanks guys.
Thanks for giving the young people a chance to answer today. It is a pity that only Selina took advantage, but it is Friday. Not many people want to do homework (even other people's on a Friday).
Thanks Selina Marie for that great answer. You gave a great one yesterday too. Why don't you join up properly and become a part of the team? That would be really good.
Have a really great weekend,
Melody.
