log 91 - log 13 = log 91/13 = log 7
log245 - log 5 = log 245/5 = log 49
so the division gives log 7 / log 49
= 0.5 answer
The value of the given expression will be equal to 0.5.
A quantity represents the power to which a fixed number (the base) must be raised to produce a given number.
log 91 - log 13 = log 91/13 = log 7
log245 - log 5 = log 245 / 5 = log 49
So the division gives log 7 / log 49
= 0.5
Therefore the value of the given expression will be equal to 0.5.
