Answer:
BRO PLEASE RECHECK THE QUESTION THAT YOU HAVE POSTED..
I UNDERSTOOD THE QUESTION AS I SOLVED IT BEFORE...
Step-by-step explanation:
3 log 2-1÷3 log 27+log 12-log 4+3 log 5
=log2^3 - 1/log27^3 + log3*4 - log4 + 3log5
=log2^3 - 1/log3^9 + log 3 + log 4 - log 4 + 3log5 (+ and - cancel)
=log8 + 9log3 + log3 + log5^3
=log8 + 10log3 + log125
USING log a + log b + log c = log (a b c)
=log [ 8 * 3^10 * 125]
=log1000 * 3^10
= log(1000) + 10 log 3
=log(10³)+10 log 3
=3 log (10)+10 log 3
=3 +10 log 3
=3 +10 × (0.477121)
= 3 +4.78
= 7.78
log property used here is log a + log b=log (a b)
HOPE IT HELPS
