Question

Can someone help me out

Answer 1

Firstly, you want to multiply (f^4)^2.
`(2*f^8*f^2)/(8f^(12))`

Next, multiply everything on the numerator.
`(2f^(10))/(8f^(12))`

Next, divide.
`(2f^(10))/(8f^(12))=(1)/(4) f^(-2)`

Now remember that f^-2 = (1/f^2), so just convert the negative powered exponent to that, and your answer will be
`(1)/(4f^2)`
