Are you familiar with the power rule?
y = axk
y' = kaxk-1
This applies whether k is an integer or a fraction, positive or negative. Try it.

Suppose
f(x) = x0.3
Note that a = 1 and k = 0.3
Then
f'(x) = 0.3x0.3-1 = 0.3x-0.7 = 0.3/x0.7

f(x) = x0.3
a = 1
k = 0.3
f'(x) = 0.3x0.3-1 = 0.3x-0.7 = 0.3/x0.7

In this problem,
a = 1
k = 0.3

You also have an inconsistency in the problem. In one place
f(x) = x0.3
and in another
f(x) = x0.03
