Directions: Find the fourth-order derivative.
1.) f''(x)=7x^5/2, f(^iv)(x)
2.) f''(x)=8x^7/5, f(^iv)(x)
basic rule for single term powers
multiply the exponent by the coefficient, keep the base, reduce the exponent by 1
so if
f '' (x) = 7x^(5/2)
f '''(x) = (35/2)x^(3/2)
do it once more
do the same for the second question
