Question

I will fan and medal!
simplify: ((a^4)/(2a^2-4a^4))*((8a^3+1)/(2a+4a^2))

Answer 1

ugh i wish you had typed it out properly :(

Answer 2

you have a calculator?

Answer 3

@Jdosio

\[\Large \frac{a^4}{2a^2-4a^4} \times \frac{8a^3+1}{2a+4a^2}\]

Answer 4

or go to www.mathway.com
then type in this equation and hit solve

Answer 5

try factoring the individual expressions first

Answer 6

if you have any choices that would help too.

Answer 7

hint: factor

\[\Large \frac{a^4}{2a^2-4a^4} \times \frac{8a^3+1}{2a+4a^2}\]
\[\Large \frac{a^4}{2a^2(1-2a^2)} \times \frac{(2a+1)(4a^2-2a+1)}{2a(1+2a)}\]

Answer 8

I used the sum of cubes formula to factor \(\Large 8a^3 + 1\)

Answer 9

you can now cancel out the 2a + 1 on the right most fraction
and the left one simplifies to

a^2
------
2(1 - 2a^2)
