Verified answer

Jawabannya:

2³+3(2³)+4(2³)=2n
8+3.(8)+4.(8)=2n
8+24+32=2n
64=2n
n= 64/2
n= 32

1 ×2³+3 × 2³+4 × 2³=2^n
= 8 × 2³=2^n
= 2³ × 2³= 2^n
= 2^6= 2^n
= 2^6= 2^n
n= 6 → Opsi A

^ = pangkat

1 . 2^3 + 3 . 2^3+ 4 . 2^3 = 2n
8 . 2^3 = 2n
2n = 8 . 8
n = 64/2
n = 32

Jika 2^n

1 . 2^3 + 3 . 2^3 + 4 . 2^3 = 2^n
8 . 2^3 = 2^n
2^3 . 2^3 = 2^n
2^6 = 2^n
n = 6
