Penjelasan dengan langkah-langkah:
nomor (5)
bagian a: log(25) + log(4) = log(25 x 4) = log(100) = 10
bagian b: log(27) - log(9) = log(27/9) = log(3)
nomor (6)
bagian a: ³√2 . √2 = 2^⅓ . 2^½ = 2^(⅓ + ½) = 2^(2+3)/6 = 2^⅚ = ⁶√2⁵
bagian b: ³√2 : √2 = 2^⅓ : 2^½ = 2^(⅓ - ½) = 2^(2 - 3)/6 = 2^(-⅙) = 1/2^(⅙) = 1/⁶√2
