Question

Simplify (IMAGE IN DESCRIPTION)
a. c^5 y^3/a b^3 x^6
b. a^-6 c^6 y^3/a^-4 b^3 x^-9
c. a^3 c^5 y^3/ b^3 x^6
d. a^3 c^5 y^3/b^3
e. none of the above

Answer 1

@bibby

Answer 2

ew. let's start with the concepts.
\(\large x^{-m}=\frac{1}{x^m}\)
\(\large \frac{a^m}{a^n}=a^{m-n}\)

Answer 3

does that say b^0 on the denominator?

Answer 4

yes. sorry the pic didn't come out clear.

Answer 5

another concept then. \(a^0=1 : x \ne 0\)
anything to the 0 is 1 (except 0)

Answer 6

okay so now we have a^-2/b^1

Answer 7

not exactly. following our rules, we have this: \(\huge \frac{a^{-2}}{b^0}=\frac{a^{-2}}{1}=\frac{1}{a^2}\)

Answer 8

okay let me write that down

Answer 9

whoops forgot about another rule. \(\huge a^m*a^n=a^{m+n}\)

Answer 10

okay what's the next step

Answer 11

let's cancel out the a's. give me a second to actually work it out on paper so I know what I'm doing

Answer 12

from what i'm getting the answer should be A?

Answer 13

same. nice

Answer 14

alright. very nice :)
