@jackthegreatest 3. (-2x^8) x 3y^9 x 2x^4 A. 2x^12y^9 B. -12x^72y^9 C. -12xy^21 D. -12x^12y^9

OpenStudy (jackthegreatest):

hmm just a bit harder i guess

OpenStudy (jackthegreatest):

\[-2x^8 \times 3y^9 \times 2x^4\]

OpenStudy (jackthegreatest):

is that right?

OpenStudy (mellamokatie):

Yeah but (-2x^8) is in perentathse

OpenStudy (jackthegreatest):

same thing haha, anyways just multiply the number and add the exponents y^9 stays the same

OpenStudy (jackthegreatest):

hopefully not confusing...

OpenStudy (mellamokatie):
