5 x - 8*x
x^5 - 8*x
Differentiate x5−8xx^{5} - 8 xx5−8x term by term:
Apply the power rule: x5x^{5}x5 goes to 5x45 x^{4}5x4
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: xxx goes to 111
So, the result is: −8-8−8
The result is: 5x4−85 x^{4} - 85x4−8
The answer is:
4 -8 + 5*x
3 20*x
2 60*x
