Question

prove that :
2log15/18 - log25/162 + log4/9 =log2

Answer 1

Step-by-step explanation:

[ Refer to the attached file ]

• Used formula!

°

$log( \frac{a}{b} ) = log(a) - log(b)$

°

$log(ab) = log(a) + log(b)$

°

$log( {a}^{m} ) = m log(a)$

Answer 2

Answer:

HEY MATE HERE IS UR ANSWER...

Step-by-step explanation:

L.H.S=

log(15/18)^2- log25/162+ log4/9

log(225/324)/(25/162) + log4/9

= log9/2+ log4/9

= log(9/2)× (4/9)

= log2

proved

L.H.S=R.H.S

HOPE IT HELPS U DEAR!!!
