Hi Redruby123;

Welcome to the forum!

Can you please bracket that off using parentheses? What do you want to differentiate with respect to?

it is how to find the dx/dp of  x=(55sqroot h+7) -90

Thanks so much!

hi Redruby123

"it is how to find the dx/dp of  x=(55sqroot h+7) -90"

That must be

surely.

In which case as

and the rule for differentiation of a power is  'multiply by the power' then 'reduce the power by 1'

so

If this is not the correct variable or you haven't followed the above, post back.

Or did you mean

?

in which case
