✔ 最佳答案
40.F ' = 2x * f + x^2 * f '
F ' (4)
= 2*4 * f(4) + 4^2 * f ' (4)
= 8*10 + 16(-2)
= 80 - 32
= 48 ..... Ans
42.
H '
= [ g*f - x*( g * f )' ] / ( g^2 * f^2 )
= [ g*f - x*( g ' * f + g * f ' ) ] / ( g^2 * f^2 )
H ' (4)
= { 5*10 - 4*[ (-1)*10 + 5*(-2) ] } / ( 5^2 * 10^2 )
= [ 50 - 4*(-20) ] / 2500
= 130 / 2500
= 13/250 ..... Ans
