anonymous · Answer

ugh i wish you had typed it out properly :(

anonymous · Answer

you have a calculator?

@Jdosio 

$$\Large \frac{a^4}{2a^2-4a^4} \times \frac{8a^3+1}{2a+4a^2}$$

anonymous · Answer

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

welshfella · Answer

try factoring the individual expressions first

anonymous · Answer

if you have any choices that would help too.

jim_thompson5910 · Answer

hint: factor

$$\Large \frac{a^4}{2a^2-4a^4} \times \frac{8a^3+1}{2a+4a^2}$$
$$\Large \frac{a^4}{2a^2(1-2a^2)} \times \frac{(2a+1)(4a^2-2a+1)}{2a(1+2a)}$$

jim_thompson5910 · Answer

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

welshfella · Answer

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)
