How do you differentiate 20((x 1)-3)?

Answer 1

Please can you clarify the following points

(i) should there be a + or - sign between x and 1?

(ii) do you mean everything in the bracket to the power of -3?

I would rewrite this as 20(x+1)^-3 or 20(x-1)^-3 where the ^ means 'to the power of'

If it is one of these last two, then differentiating you would get

-3*20*(x+1)^-4 or -3*20*(x-1)^-4 (8 means multiplied by )

or simplifying

-60(x+1)^-4 or -60(x-1)^-4
