You can put this solution on YOUR website!
if log5 = 0.699
log7 = 0,845 and
log3 = 0,4771
then log_210 = 


log 210 = log (10 * 7 * 3)

log (10 * 7 * 3) = log 10 + log 7 + log 3

Since log 10 = 1, and base 10 is being used, then log 5 = 0.699 is NOT needed.

Thus, log 210 becomes: log 10 + log 7 + log 3, which becomes: 1 + .845 + .4771, or highlight_green%28highlight_green%282.3221%29%29
