I need to simplify:
(49c^6)^(-3/2)
I know that the answer is 1/343c^9. But I have noo idea how they got it?
Thank you!
Ok, I understand what happened with my 1st question... now i'm stuck on another
How does (4^-2)+(3^-1)/(3^-2)+(2^-3) become 1(23/34)?
This is waht I'm doing:
= (1/4^2+3^-1)/(1/3^2+2^3)
= (1/16+3)/(1/9+8)
= (1/19)/(1/17)
= (1/19)*(17/1)
= 323.
I have no idea where I am going wrong. thank you for any tips you might have!
