diketahui log 3 basis 2 = x dan log 5 basis 2 = y Nyatakan nilai dari log 225 basis 2 dalam X dan Y

[tex] {}^{2} log3 = x \: \: \: \: \: \: {}^{2} log5 = y \\ {}^{2} log225 = \frac{ {}^{2}log225 }{ {}^{2}log2 } = \frac{ {}^{2} log {3}^{2} {5}^{2} }{1} \\ = {}^{2} log {3}^{2} + {}^{2} log {5}^{2} = 2(x) + 2(y) = 2(x + y)[/tex]
