Question

Cari lah hasil dari
1. (1/8)^1/3 + (8/27)^1/3 - (1/64)^1/6
2.(27/64)^1/3 + (1/8)^1/3 - (1/27)^1/3
Plis tolong pake jalannya

Answer 1

1. (2^-3)^(1/3) + (2³/3³)^(1/3) - (2^6)^(1/6)
= 2^ (-3/3) + (2/3)^(3/3) - 2^(6/6)
= 2^(-1) + (2/3) ^ (1) - 2 ^ (1)
= 1/2 +2/3 -2
= .... (hasilnya itung sendiri ya, tinggal samain penyebut nya aja)

2. (3^3/4^3)^(1/3) + (2^-3)^(1/3) - (3^-3)^(1/3)
=  (3/4)^(3/3) + 2^(-3/3) - 3^(-3/3)
= 3/4 ^(1) + 2^(-1) - 3^(-1)
= 3/4 +1/2 - 1/3
= .... (itung sendiri jg XD)
