open parenthesis, V minus n (times) b, close parenthesis
could also be:
(V-n x b)
So I would not use the word "times"
I'd call it "nb"
Interested in Language
Please, dear teachers, could you help me out with this?
I am trying to speak an equation, so I'd like to know how to do that.
The equations is:
And this is my shot/try:
open brace, P plus a (times) n square over v square close brace, open parenthesis, V minus n (times) b, close parenthesis, is equal to n (times) R (times) T.
where '(times)' is optional.
So, Is that right and usual?
Thank you

How'd you call this:
a) 2^3 = 8
b) 2^4 = 16
c) 2^5 = 32
d) 2^n
Thank you in advance

That is the equation given by marciobarbalho. Multiplication takes precedence over subtraction. Did you mean:
(V-n) times b; or b(V-n)
The relocation of the parenthesis takes care of that.
a) 2^3 = 8
2 (to the) (raised to the) third power equals 8
...to the fourth power/to the fifth power/to the nth power

The equation is (V - nb) or (V - n*b).
In Portuguese, we usually call x^2 like this:
x square.
Do people always call it like that?
where 'square' is related to two equal sides of something, x*x
x^3 is very common people say something related to 'cube', meaning 3 equal sides of something.
How'd you call that in English?
x^4 is called "raised to the fourth power"
Thank you.
Yes, X squared, x^2 or X2 (except the 2 should be at the top of the X, not the bottom) is easy, as is X cubed. But from then on, 'to the power of', or X to the fourth' is usual, than something like 'X quadrupled' which is a mouthful.
I wouldn't call the square brackets "braces"; in my understanding a brace is a curly bracket ({}). But I'm not a mathematician or a physicist, and I don't know whether they observe different conventions.
And a quantity raised to the power 2 is - in Br E at least - "squareD".
b
Then, x^2 is called x squared and x^3 is called x cubed. From then on, x to the th-power.
Thank you guys.
Further reflection about that "sometimes". I think it's more common to keep the word "power" when talking about larger numbers - the time since the Big Bang will be 't to the Nth power', but N^5 may well be expressed as "N to the fifth".
b
