Question

simplify
2 2
-- x --
3a a^2

Answer 1

did u try to do it?

Answer 2

Do I cross multiply? (I dont always pay attention in math......)

Answer 3

when multiplying fractions u multiply top by top and bottom by bottom

Answer 4

u cross multiply when there is an equal sign between them,, but when there is a multiplication sign u simply multiply top by top and then bottom by bottom

Answer 5

But what if its something like in the problem when the denominator is a variable to the power of 2? does the variable become one?

Answer 6

when both variabls are the same,, like in this question u have 3a and a^2
that becomes 3a^(2+1)=3a^3
but if they were different like for example a^2 and b
u just write it as a^2b

Answer 7

oh, ok. had to think about that for a second.

Answer 8

so now do u know how to find the product of these fractions?

Answer 9

I think so. would the answer be 4 over 3a^3?

Answer 10

yup

Answer 11

yay!

Answer 12

\[2/3a x2/3a ^2=4/3a ^3\]
