What's to the 2nd power? (2*[^2])

Actually it's 56

The point of the original post was to place parenthesis so that it was true when order of operations was applied.

What is 2x^2-8/(x-2)^2 when x = 0? Furthermore, at what point is that equation constant?

-2, and "constant at a given point" doesn't make sense for an equation.

no one really answerd my 2nd question

7 8ths/5

**rubah** · 10-09-2005, 01:34 AM

7/8*1/5=7/40?

no.
you're wrong (for once)

and it's 5/1, not 1/5
(other than that, you have it right)

**rubah** · 10-09-2005, 01:41 AM

You said 7/8 divided by five. that's the same as multiplying by 1/5.

**I gots a latta moe info!!** · 10-09-2005, 01:46 AM

the real answer is 4 3/8
7*5=35
8*1=8
35-/-8=4.3
4 3/8
get it?

**rubah** · 10-09-2005, 01:54 AM

That would be multiplying 7/8 by 5, not dividing. Generally the / sign denotes division. Given your original problem of 7 8ths/5, that would be 7/8 ÷ 5.

mental math, the $calc() function in mIRC and the windows calculator all give me 0.175 or 7/40

**I gots a latta moe info!!** · 10-09-2005, 02:03 AM

you do division, eventually. 35/8. but you're right, that's multiplying, not division.

that's just how I was taught it.

I need more problems. Gimme problems!!!
(keep it easy, though)

Find the integral of (e^x)sinxdx. Use the Looper Method by Parts.

The math you're doing bores me.

**I gots a latta moe info!!** · 10-09-2005, 03:08 AM

I asked for something easy!!! I just say I'm 18!!! I'm younger than that!!!!

(and what is e and x???)
and what does integral mean!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!

I'm 17. ;]

And come now, that's pretty easy. It's just integration by parts that you do twice.

e = 2.71828183
x is a variable.
