Q. [ Last ]

f(y) = y! + 64(y) × y!!
f(5) = .....

​

Answer 1

Penjelasan dengan langkah-langkah:

f(y) = y! + 64(y) × y!!

f(5) = 5 x 4 x 3 x 2 x 1 + 64(5) x 5 x 3 x 1

f(5) = 20 x 6 + 320 x 15

f(5) = 120 + 4.800

f(5) = 4.920

semoga membantu

Answer 2

Penyelesaian :

• f(y) = y! + 64(y) × y!!

• f(5) = 5! + 64(5) × 5!!

• f(5) = ( 5 × 4 × 3 × 2 × 1 ) + 64(5) × 5!!

• f(5) = ( 20 × 3 × 2 × 1 ) + 64(5) × 5!!

• f(5) = ( 20 × 6 × 1 ) + 64(5) × 5!!

• f(5) = ( 120 × 1 ) + 64(5) × 5!!

• f(5) = 120 + 64(5) × 5!!

• f(5) = 120 + ( 64 × 5 ) × 5!!

• f(5) = 120 + 320 × 5!!

• f(5) = 120 + 320 × ( 5 × 3 × 1 )

• f(5) = 120 + 320 × ( 15 × 1 )

• f(5) = 120 + 320 × 15

• f(5) = 120 + ( 320 × 15 )

• f(5) = 120 + 4.800

• f(5) = 4.920
