Answer 1

hope it's helps .....

Answer 2

ANSWER :

 

3 - log 12

$3 log2-\frac{1}{3}log27-log4+3log5\\\\\implies log2^3-log27^{1/3}-log4+log5^3\\\\\implies log8-log3-log4+log125\\\\\implies log(\frac{8\times125}{4\times3})\\\\\implies log(\frac{1000}{12})\\\\\implies log1000-log12\\\\\implies log10^3-log12\\\\\implies 3-log12$

LAWS OF LOGARITHM

Use log ( abc ) = log a + log b + log c .

Eg :

log ( 4 ) = log 2 + log 2

log 10 = log 5 + log 2

Use log aᵇ = b log a

Eg :

log 4 = 2 log 2

log 8 = 3 log 2
