algebra I have f'(x)= -7(3x+65)^(-8) (3)
when I move the first part down (over a fraction) do I invert just the power, or the -7 as well?
I.e. f'(x)= 3/7(3x+65)^(8) or would it be 3/(-7(3(x+65)^(8)

The way you have it written, Just the power.
The neg. exponent only applies to what you have in the brackets (3x+65)

Ok, thanks.  Looking at it a second time, can i rewrite it " f'(x) = -21/(3x + 65) ^(8)  ?

If the 3 is multiplied by the 7, yes

Ok, thanks.  Sometimes I forget the basic stuff after a few years. lol
