Question

Please help me .

Divide and simplify the terms in this polynomial
((-ab5)/(cd2))3

Answer 1

there are no common factors so its simply a case of

\[\frac{(-a)^3 \times (b^5)^3}{(c)^3 \times (d^2)^3}\]

simply the power of a power by multiplying powers

\[(x^a)^b = x^{a \times b}\]

hope this helps

Answer 2

im still confused :/

Answer 3

ok... so do you know much about index laws...?

Answer 4

as the cube, power of 3, is operating on every term in the expression...

Answer 5

i know the basics that it though idk how do the whole divide and what not

Answer 6

well to be able to divide... you need common factors... you expression has none..

here is an example

\[\frac{10x^3y}{4xy^2} = \frac{5x^2}{2y}\]

the fraction on the left has 2xy as a common factor... it can be cancelled from the numerator and denominator.

you don't have any common factors in your question... so it can't be simplified beyond the powers...

Answer 7

it cant be simplified after \[5x ^{2}/2y\]

Answer 8

no it can't, just like your question

Answer 9

unless you are using negative powers.
