2. What is the simplified form of each expression? 7x^-8 x 6x^3 A. 42/x^5 B. 1/42.x^5 C. 42x^11 D. 13x^-5 @jackthegreatest

OpenStudy (mellamokatie):

Traveling is awesome where?

OpenStudy (jackthegreatest):

easy too, just multiply the 6 and 7

OpenStudy (jackthegreatest):

and the franctions add them (in this case subtract)

OpenStudy (jackthegreatest):

whoops not fractions, exponents

OpenStudy (mathmale):

You may find it instructive and helpful to rearrange the 4 terms of your expression. Try simplifying 7^6 * x^(-8) * x^3.

OpenStudy (sshayer):

\[=7 \times 6 x^{-8+3}\]

OpenStudy (jackthegreatest):

@MellamoKatie so what is your answer?

OpenStudy (mellamokatie):

So I got 42 for 7x6 and -11 for the exponents

OpenStudy (mellamokatie):

So C?

OpenStudy (jackthegreatest):

-8+3 is...

OpenStudy (mellamokatie):

-11?

OpenStudy (mellamokatie):

OHHH ADDING

OpenStudy (jackthegreatest):

lol

OpenStudy (mellamokatie):

-5?

OpenStudy (jackthegreatest):

yep x^-5

OpenStudy (jackthegreatest):

how could that be rewritten?

OpenStudy (mellamokatie):

Hmm 42/x^5?

OpenStudy (jackthegreatest):
