3log2 - 10g27 + log12 – log4 + 3log5​

Answer 1

Step-by-step explanation:

3-log9 must be the answer

when we simplify it

Answer 2

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
