Can you explain how to do this?
(2x^2y^3)(-3x^3y^4)(6xy)=?

id stack them to keep track of it better
OpenStudy (anonymous):
What do you mean?
OpenStudy (amistre64):
2 x^2 y^3
-3 x^3 y^4
6 x y
i mean, id stack them so that i could keep track of them better :/
OpenStudy (anonymous):
ohh okay
OpenStudy (jiteshmeghwal9):
\[(2.-3.6)x^2y^3x^3y^4xy\]

my bad
OpenStudy (amistre64):
like bases add exponents; and constants just get mulitplied together
OpenStudy (jiteshmeghwal9):
multiply the constants & multiply the like terms to gt ur answer
OpenStudy (jiteshmeghwal9):
gt it @maherman97 ???
OpenStudy (anonymous):
no... haha what do you mean the constants?

constants=numerical terms
OpenStudy (jiteshmeghwal9):
such as 3,5 etc.
OpenStudy (anonymous):
well can you walk me through the steps?
OpenStudy (anonymous):
i would start by multiplying (6xy) by 2x^2y^3) get the answer and the multiplying the answer by (-3x^3y^4)
OpenStudy (anonymous):
how do you multiply the first part?

OpenStudy (anonymous):
ok . (6xy)(2x^2y^3)= 12x^3y^4 using exponents rules.
OpenStudy (anonymous):
okay so then why do i multiply that by (-3x^3y^4)
OpenStudy (anonymous):
that what the operator dose.
OpenStudy (anonymous):
the what???
OpenStudy (anonymous):
im soooo confused!

(A)(B)(C) means A multiply B multiply C as an example .
OpenStudy (anonymous):
rightt....
OpenStudy (anonymous):
So then i multiply 12x^3y^4 by (-3x^3y^4)
OpenStudy (anonymous):
SO THAS why we use the operator (multiplication) thats what i mean by "operator" hope that helps
OpenStudy (anonymous):
okay so can you show me the steps into multiplying 12x^3y^4 by (-3x^3y^4)

OpenStudy (anonymous):
sure.
OpenStudy (anonymous):
so what do i do first?
OpenStudy (anonymous):
1>multiply 12by -3 = -36
2> x^3by x^3 = x^6
3> y^4 by y^4= y^8
OpenStudy (anonymous):
so it would be -36x^8y^8?
OpenStudy (anonymous):
x^6* my badd

okay thanks soooo much!
OpenStudy (anonymous):
ive got another for you
OpenStudy (anonymous):
i would appreciate a "BEST REPONSE " if you think so?? :)
OpenStudy (anonymous):
thanks
OpenStudy (anonymous):
sooo if i have \[(3x)^{3}(4x)^{2}\] would the answer be 216?

no (3x)3(4x)2 thats not the same. be careful mate.. :)
OpenStudy (anonymous):
so what would it be? and what did i do wrong?
OpenStudy (anonymous):
\[(3x)^3\] is not the same as
\[3x^2\] = henc \[(3x)^3\]=\[3^3 x^3= 27x^3\]
and \[3x^3=3x^3\]
