Just a question about your problem, I just wanted to make sure if the problem is not a typo. Is the 2x part is written in the form on the exponential function such as 2^{x}^{3 }or do you mean 2x^{3}? (where only the 3 is the exponent).^{ }

(2x^2-7)^4 = f (as per you stating this is how it should be written)

Follow the steps for power rule, but now you'll have to differentiate what is inside the parenthesis. Technically you have done this with say x^2, which is 2x * 1 (derivative of x is 1)
