[tex]\sf \: diketahui \: \: f(x) = {}^{3} log(4x + 7)[/tex]
[tex]\sf \: f(5) = ....[/tex]
........
Penjelasan dengan langkah-langkah:
[tex]\sf f(x) = {}^{3} log(4x + 7)[/tex]
[tex]\sf \: f(5) = {}^{3} log(4(5) + 7)[/tex]
[tex]\sf \: f(5) = {}^{3} log(20 + 7)[/tex]
[tex]\sf \: f(5) = {}^{3} log27[/tex]
[tex]\sf \: f(5) = {}^{3}log {3}^{3} [/tex]
[tex]\sf \: f(5) = 3.1[/tex]
[tex]\sf \: f(5) = 3[/tex]
