Question

evaluate this sum and get the chance of winning brainliest

Answer 1

$log_{a}(bc) = log(bc) \div log(a)$
similarly this will happen to all the log terms
after this take l.c.m. in the denominator
you will get log(bc)+log(a)
after this apply another formula
log(a) + log(b)=log(ab)
similarly denominator will be log (abc)
and numerator will be log a , log b ,log c
take l.c.m. and again apply the formula you will get your answer that is 1

Answer 2

by this process we can say that the answer is 1
