log 10 means
log 10 to the base 10
that ts equal to 1
so,
log10=1
log 10 to the base 10
that ts equal to 1
so,
log10=1

@sumit
Log 5=log(10/2).coz,10/2=5
Log 5=log(10/2).coz,10/2=5

@Kasthuri
log 75= log(5*5*3) = log(5*5)+log(3), because log m*n=log m+log n
=2 log5 +log3
=2 log(10/2)+log3
=2(log10-log2)+log3
=2(1-.3010)+..4771
=2*.699+.4771
=1.398+.4771
=1.8751
