Q. Find the derivative of the following function.y=e8x6+5x5Answer: y′=
Identify u as exponent: To find the derivative of the function y=e8x6+5x5, we will use the chain rule. The chain rule states that the derivative of eu, where u is a function of x, is eu times the derivative of u with respect to x.
Find derivative of u: First, let's identify u as the exponent of e. In this case, u=8x6+5x5.
Apply power rule: Now we need to find the derivative of u with respect to x, which is u′. To do this, we apply the power rule to each term separately. The power rule states that the derivative of xn is n∗x(n−1).
Apply chain rule: The derivative of the first term, 8x6, is 48x5 because we multiply the exponent 6 by the coefficient 8 and then decrease the exponent by 1. The derivative of the second term, 5x5, is 25x4 because we multiply the exponent 5 by the coefficient 5 and then decrease the exponent by 1. So, 48x50.
Final derivative: Now we can apply the chain rule. The derivative of y with respect to x, y′, is eu times u′. So, y′=e8x6+5x5×(48x5+25x4).
Final derivative: Now we can apply the chain rule. The derivative of y with respect to x, y′, is eu times u′. So, y′=e8x6+5x5×(48x5+25x4).We have found the derivative of the function without any mathematical errors. The final answer is y′=e8x6+5x5×(48x5+25x4).
