Come si differenzia f (x) = (3x ^ 5 - 4x ^ 3 + 2) ^ 23 usando la regola della catena.?

Risposta:

#f '(x) = 69x ^ 2 (3x ^ 5 -4x ^ 3 + 2) ^ 22 (5x ^ 2 -4) #

Spiegazione:

Ricorda: regola della catena:

# "Derivata di" f (g (x)) = f '(x) g (x) * g' (x) #

Derivata della regola di potenza e catena: #f (x) = (g (x)) ^ n = f '(x) = n (g (x) ^ (n-1)) * g' (x) #

Dato #f (x) (3x ^ 5 -4x ^ 3 + 2) ^ 23 #

#f '(x) = 23 (3x ^ 5-4x ^ 3 + 2) ^ (23-1) * colore (rosso) (d / (dx) (3x ^ 5 -4x ^ 3 + 2) #

# = 23 (3x ^ 5 -4x ^ 3 + 2) ^ 22 colore (rosso) ((15x ^ 4 -12x ^ 2 + 0) #

# = 23 (3x ^ 5 -4x ^ 3 + 2) ^ 22color (rosso) (15x ^ 4 -12x ^ 2) # o

per fattore il più grande fattore comune #color (blu) (3x ^ 2) #a partire dal # 15x ^ 4 -12x ^ 2 #

#f '(x) = 23 * colore (blu) (3x ^ 2) (3x ^ 5 -4x ^ 3 + 2) ^ 22 (5x ^ 2 -4) #

Semplificare:

#f '(x) = 69x ^ 2 (3x ^ 5 -4x ^ 3 + 2) ^ 22 (5x ^ 2 -4) #
