f(8)
Jawaban:
399
Penjelasan dengan langkah-langkah:
f(x) = 55 + x!! - 5x
f(8) = 55 + 8!! - 5(8)
f(8) = 55 + (8x6x4x2) - 5(8)
f(8) = 55 + 384 - 40
f(8) = 439 - 40
f(8) = 399
Salam kenal...
f(x) = 55 + x!! - 5x
f(8) = 55 + 8!! - 5(8)
f(8) = 55 + ( 8 × 6 × 4 × 2 ) - ( 5 × 8 )
f(8) = 55 + ( 48 × 8 ) - 40
f(8) = 55 + 384 - 40
f(8) = 439 - 40
f(8) = 399
