Question: Hi Kate, Suppose that you call your function y, then
To differentiate y first take the natural log of both sides and use the fact that log(a^{b}) = b log(a). Thus
Now differentiate both sides with respect to x to get
To complete the problem, substitute y = 5^{5x  2} and evaluate when x = 0.8.
Cheers,
