[tex]\displaystyle \frac{\left ( ^2\log 5+^3\log 5 \right )^{36}\log 0,2}{^2\log 5~^3\log 5}[/tex]
[tex]\displaystyle \frac{\left ( ^2\log 5+^3\log 5 \right )^{36}\log 0,2}{^2\log 5~^3\log 5}[/tex]
PEMBAHASAN
ᵃlog b = log b / log a
log aⁿ = n log a
log ab = log a + log b
log 36 = log 6² = 2 log 6
log 0,2 = log (2/10) = log (1/5) = log 5⁻¹ = - log 5
