Answer 1

a) log3(15) - log3 (5)
log3 (3)
1

b) log5 (25 . 125)
log5 (3125)
log5 ($5^{5}$)
5

c) log5 ($5^{125}$)
125log5 (5)
125 . 1
125

d) log3 ($\frac{27 . \sqrt{3} }{ \sqrt[3]{3} }$)
log3 (3 $\frac{19}{6}$)
$\frac{19}{6}$

4) log2(7) log7(13) log3(2)
$\frac{log3(7)}{log3(2)}$ . log7(13) log3(2)
log3(7) log7(13)
