same as: log7 49 + log7 x + log7 y + log7 z = 2 + log7 x + log7 y + log7 z
OpenStudy (anonymous):
Where does the 2 come from I know it has to do something with 7^2=49 but I dont understand how to get it
OpenStudy (yttrium):
do you know that log(a) b = c is same as a^c = b In this case, we'll have log7 49 = 2 because 7^2 = 49
