Best ResponseYou've already chosen the best response.0We can write it as \[\log_{5}1\log_{5}125 \] .................. (1) then we know that logarithm of 1 with any base is zero so the (1) becomes \[0\log_{5}125\] ................... (2) now we can write this as \[\log_{5}5^{3}\] ................... (3) now this becomes \[3\times \log_{5}5 \] ................... (4) and as we know \[\log_{5}5=1 \] ...................... (5) so answer is 3
