Best ResponseYou've already chosen the best response.5That's a good point FFM so lets do simplification that you know, but a little more intense: I think I need to make sure you can simplify bigger things:\[\frac{x^2y^5z}{xy^9z^3}\]

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.5\[x^{a}=\frac{1}{x^a}\]so it's probably nicer to rewrite your expression with all positive exponents in this way.

Inopeki

Best ResponseYou've already chosen the best response.0Oh right, all negative exponents make the "total number" divided by one.

TuringTest

Best ResponseYou've already chosen the best response.5Oh dear... I have my answers about x^0=1 (not true for x=0), but I'm sure FFM would not approve of them :/ @inopeki, yes now rewrite it as 1 fraction...

TuringTest

Best ResponseYou've already chosen the best response.5well I have a very simple proof of it and I can show why it is not true for x=0 what more do I need in your opinion?

Best ResponseYou've already chosen the best response.1Can you explain the second rule intuitively?

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.5no, I was thinking more of how easy it is to show x^ax^b=x^(a+b) intuitively, the other is tricky to me.

TuringTest

Best ResponseYou've already chosen the best response.5@ inopeki you can put the x on top, it means the same thing and looks nicer

Best ResponseYou've already chosen the best response.1Tha's whats Inopeki is using right ?

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.5basically Inopeki do you see the connection between what you are doing and the rule for multiplying exponents like\[x^ax^b\]?

Inopeki
 4 years ago
Best ResponseYou've already chosen the best response.0Yeah, but does that mean that it becomes x  ? yz^6

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.5no because y and z are different bases notice the rule above had both base x.

Inopeki
 4 years ago
Best ResponseYou've already chosen the best response.0YEah but then i dont see the connection..

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.5just that dividing and multiplying are inverse operations x^a=x*x*x*...*x (a times) x^b=x*x*x*...*x (b times) so if we have a=3 b=2 we get x^a  x^b x*x*x == x x*x which is x^(ab) if we have (x^a)(x^b) we get (x*x*x)(x*x)=x*x*x*x*x=x^(a+b) so the rules for exponents here come directly from their definitions. You can count the x and see that this relationship holds.

Inopeki
 4 years ago
Best ResponseYou've already chosen the best response.0I know about that, like x^2*x^8=x^10

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.5right, I want you to see how that and the rule for division are inverses of each other for a reason...

Best ResponseYou've already chosen the best response.03xy(3x^3*y^3/3xy)+3xy(6xy/3xy)+3xy(9x^2*y/3xy)=3xy(x^2*y^2+2+3x)?

TuringTest

Best ResponseYou've already chosen the best response.5Multiplex? no I think you're thinking of 'multiplicity' but this is the 'difference of squares' \[a^2b^2=(ab)(a+b)\]

Best ResponseYou've already chosen the best response.5The fundamental theorem of algebra: "the sum of the multiplicity of the roots of a polynomial is equal to its order" difference of squares\[a^2b^2=(ab)(a+b)\]both important, but very different

TuringTest

TuringTest
 4 years ago
Best ResponseYou've already chosen the best response.5(p^2q^2)(p^2+q^2) stop here we cannot factor the second set of parentheses, it is not a /difference/ of squares, it is a /sum/ of squares, and we have no formula for that. check that (a+b)(a+b) is not a^2+b^2 so only factor the one that is a /difference/ of squares

Inopeki

Best ResponseYou've already chosen the best response.0(pq)(p+q)(p^2+q^2) You said i had to do difference in squares 2 times? Btw, lets move to a new thread, this one is starting to lag a little bit

TuringTest

Best ResponseYou've already chosen the best response.5That is above correct, you did difference of squares twice: p^4q^4 (p^2q^2)(p^2+q^2) <once (pq)(p+q)(p^2+q^2) <twice ok new thread...
