f(x)= -3(5x-2)4

Question

question on maths calculus on differentiation

Answer 1

f(x) = -3(5x - 2)⁴

f'(x) = -3(5)(4)(5x-2)³ = -60(5x-2)³

You have to take the -3 times the derivative of (5x - 2) which is -3 ·5 = -15

multiplied by the derivative of (5x-2)⁴ which is 4(5x-2)³

By the way, I have to copy the answer then Update the Answer , then open the problem again and copy the answer back in the blank space then Update the Answer again.

I complained to Wyzant but the problem still exists and I've rebooted my computer and can't find any errors.
