derivative of 7^root(x-3)

Arturo O.

Fred,

The way the problem is stated, with the "^" symbol, it looks like you want the derivative of 7√(x-3).

Is that correct, or did you mean 7/√(x-3) ?

OK, it looks like Nicolas worked it assuming it was 7/√(x-3).  I try the other solution later tonight, unless someone beats me to it.

y = 7^root(x-3) is an exponential; the derivative of an exponential starts by copying the exponential, then applying the factor ln(base), and then applying the chain rule.

I get y'  = 7√(x-3)•ln 7•½•(x-3)

I got the same solution, using the logarithmic derivative.
