Yeah, like everyone said, it's a forum where you can answer and ask questions about math.
At times, people post some stuff that are fun, but there's been like a "dead" streak for about 2 months now...
You're not forced to post something that is not related to math. In fact, you'll probably get more views and likes when you post something that is funny...
But yeah, like ElectricPalov said, for private conversations, use messaging.
You know, I've been waiting for something other than math to pop up for a very long time... so this is interesting
Don't worry, it seems like everyone here likes new members.
I'm hoping everyone will liven things up here now. Not everything needs to be math-y...
But...yeah. Don't post random stuff for no reason and continuously posting un-math-y stuff isn't really a good idea. There are people who need help with their math here.
And no, this post is not considered spam. You can post something like this occasinally and everything will be fine.
Well, let's simplify.
When there dividing numbers with the same base but with different exponents, we subtract the second exponent from the first exponent.
(m^2/5) / (m^(-8/5))
Subtract the exponents. 2/5 - (-8/5)
That would be 2/5 + 8/5, which equals to 10/5.
10/5 is 2. So the exponent would be 2.
Our final answer would be m^2
New Year, New Start, New Answer!
First answer of the year for me.
Alright, I'll try to explain this the best I can using a keyboard.
The equation is x^2(6x - 11)(7x - 8) = 0
So, you have to figure out what you can put in for x for the whole thing to equal 0.
Roots mean possible solutions.
Let's "divide" the equation into 3 parts.
We know that anything multiplied by 0 is 0.
And 0 to the power of anything is still 0.
So if you plug in 0 for x^2(6x - 11)(7x - 8) = 0, You get 0 (it would look like "0(6x-11)(7x-8)" )
So the first root is 0.
Next, let's look at the (6x - 11) part.
Remember that anything multiplied by 0 is 0.
So, 6x - 11 must equal to 0.
So another root is 11/6.
Finally, let's look at (7x-8)
That should also equal 0, no matter what it is multiplied by.
The last root is 8/7
So the three roots are 0, 11/6, and 8/7.
I agree with GingerAle.
This joke isn't racist, it's a pun. These days, many people are trying to point out everything as racist. They're like, "That's so racist!" or "Are you being racist?" in a loud voice. As long as you are not insulting Russians just because they are Russians, you are fine. Your friends just want something to make fun of. Ignore their comments and they'll get over it (if they already haven't).
It's been a while since I've posted a math explanation...
Alright, you'll have to subtract those two equations, but you have to make one term (with variable) the same.
Let's allow both equations to have 3x.
3x+2y=16 already has 3x inside, so leave it alone.
So for x-y=-3 to have 3x, you multiply 3 to every term in that equation.
Let's subtract now.
-5y = -25
So we have -5y = -25
Divide both sides by -5 and you get y=5.
Plug 5 for y in any equation to get x. I'll use the first one.
x = 2
So x=2, y=5.
