Question 832605
log10 1000+ log7 343

log10(1000) + log7(343)
{{{log10(10^3) + log7(7^3)}}}
Since {{{log10(10^3)}}} means 10 raised to what power is {{{10^3}}},
this makes {{{log10(10^3)}}} = 3 .
Since {{{log7(7^3)}}} means 7 raised to what power is {{{7^3}}},
this makes {{{log7(7^3)}}} = 3 .
So {{{log10(10^3) + log7(7^3)}}} = 3 + 3 = 6
