Kuis +50 a(n) = 2ⁿ+2n+n²-2⁻¹n³ a(4) =

Penjelasan dengan langkah-langkah:

a(4) = 2⁴ + 2.4 + 4² – 2⁻¹.4³

a(4) = 16 + 8 + 16 – 1/2¹.64

a(4) = 16 + 8 + 16 – 1/2.64

a(4) = 16 + 8 + 16 – 32

a(4) = 24 + 8 – 32

a(4) = 32 – 32

a(4) = 0

Penjelasan dengan langkah-langkah:

a(n) = 2ⁿ+2n+n²-2⁻¹n³

a(4)

==>

a(4) = 2⁴ + 2(4) + 4² – 2^-1 (4)³

a(4) = ( 2 × 2 × 2 × 2 ) + 8 + ( 4 × 4 ) – 1/2¹× 64

a(4) = 16 + 8 + 16 – 32

a(4) = 24 + 16 – 32

a(4) = 40 – 32

a(4) = 8

Semoga Membantu CMIW^_^
