Final answer:
The derivative of y = 3x^5 is dy/dx = 15x^4.
Step-by-step explanation:
To find the derivative of the function y = 3x5, we can use the power rule of differentiation. According to the power rule, when you have a function of the form y = axn, the derivative is given by dy/dx = anxn-1.
Applying the power rule to the function y = 3x5, we have dy/dx = 5 * 3x5-1 = 15x4.
Therefore, the derivative of y = 3x5 is dy/dx = 15x4.
