Answer 1

Jawaban:

logar!tma

persamaan (1)

[tex] {}^{3} log( \sqrt{3} ) + 2. {}^{3} log( \frac{1}{3} ) + {}^{3} log(81) \\ {}^{3} log( {3}^{ \frac{1}{2} } ) + 2. {}^{3} log( {3}^{ - 1} ) + {}^{3} log( {3}^{4} ) \\ \frac{1}{2} + 2( - 1) + 4 \\ \frac{1}{2} - 2 + 4 = \frac{1}{2} + 2 = \frac{5}{2} [/tex]

persamaan (2)

[tex] log_{3}(9) + log_{3}(27) \\ log_{3}( {3}^{2} ) + log_{3}( {3}^{3} ) \\ 2 + 3 = 5[/tex]

persamaan (3)

[tex] log_{2}( \frac{1}{8} ) + log_{2}(16) \\ log_{2}( {2}^{ - 3} ) + log_{2}( {2}^{4} ) \\ - 3 + 4 = 1[/tex]
