Which of the following options is NOT a derivative of
y = (1+2x)4/5
A. y'(x) = (2) (4/5) (1+2x)-1/5
=(8/5)(1+2x)-1/5
B. y''(x) = (2)(-1/5)(8/5)(1+2x)-6/5
= (-16/25)(1+2x)-6/5
C. y'''(x) = (2)(-9/25)(-7/5)(1+2x)-11/5
= (197/125)(1+3x)-11/5
D. y'''(x) = (2)(-16/25)(-6/5)(1+2x)-11/5
= (192/125)(1+2x)-11/5
y'''(x) = (2)(-9/25)(-7/5)(1+2x)-11/5
= (197/125)(1+3x)-11/5
is not a derivative of
y = (1+2x)4/5
