Yep.

I'm doing this graded exam for homework and it's on monomials and multiplying them. I pretty much understand it, but I have one question.

IF ANYONE UNDERSTAND WHAT I AM TALKING ABOUT, PLEASE HELP!!!

OK so the problem is

(7t)(-s(exp2)t)(2s(exp3))

the exp means that the number is an exponent.

Now I understand most of it, but I'm not sure if I have to multiply 7 and 2 (the one with the s behind it), because 7 has a T and 2 has an S. What do I do!?

i hate math

Well I don't know the answer, but you are right. Math is pure evil. It's sad but in the real world we will never need Algebra.

PZelda · 12-07-2004, 06:37 PM

From what I remember, you have to multiply the innermost ()'s first...lemme figure that out...

(7t)(-s^2t)(8s)

Ummm...if I did this right, I got -8s²7t as my answer...

You have to move the s to the front and the t has to be behind it...because it goes in ABC order. Yeah, I'm no math expert, but I remember doing this when I was in HS and it was pretty easy for me...but I graduated 2 years ago.

I probably totally did that wrong...

You can multiply anything with different variables. You just can't add them and turn them into a monomial.

If I read it correctly, I think the answer is -14t(^2)s(^6).
Anybody get the same thing?

Caffeine King · 12-07-2004, 06:49 PM

I asked my sister, she's in Algebra...

She said it was...

-7texp(3)s + 14texp(2)s

Oy! Call me if you get to a 2+2 type question.

Hollow · 12-07-2004, 06:56 PM

would this be it?

(7t)(-s²t)(2s³)

anyway, i haven't done this type of algebra since 8th grade but as far as i remember you would multiply the 7 and 2, which would come out as 14ts³. you'd include the variables (t and s) and the variable exponents (2 and 3) since they're unknown, and are supposed to be multiplied by the known (7 and 2, which is 14).

so, (7t)(2s³) = 14ts³. i tested it and it's true.

That's impossible. He's doing monomials (meaning it's one term with one nonzero number and no + or - signs).

Oh, good you got the exponents in. But since you're multiplying two t's, you'd get t squared. And since s is negative, the answer would be negative as well. And s would be to the power of six, since you'd have to multiply their exponents (2 times 3). Right? I haven't done this since high school...so I may be off.

But as for math being evil, I disagree. It could be pretty fun. Especially if you had good teachers.

I didn't include the (-s²t), i just multiplied (7t) and (2s³) since he was asking if you multiply the 7 and 2 being that they have different variables.

Oh, got it.

Hollow · 12-07-2004, 07:24 PM

ok, i solved the whole thing..

14t²(s5)

5 being the exponent. i'm certain it's correct.

Ooh that's right. You add exponents when multiplying.
