: I got the answer to the question
: but I am still not sure how far you go to simplify

: the text book has simplified it like that
: [(a^3)(b^3)]/[(a+b)^3}
: why why not like ((a/b)/(a+b))^3
: I looked at the rules and it seemed right.

where did you come up with (a/b)?

if the problem is to simplify [(a^3)(b^3)]/[(a+b)^3] then the answer should be

[a³b³]/[a³ + 3a²b + 3ab² + b³]

however, if you want a reduced fraction in factored form it should be

[a³b³]/[(a + b)³]

or if asked for reduced exponential form, it should be

[(ab)/(a+b)]³

- no need to feel sorry... you had one of the "forms" -nt- T.Gracken 07:53:36 10/02/02 (0)
