Sum of logarithms with same base | Algebra II | Khan Academy - YouTube YouTube Start of suggested clip End of suggested clip So this thing right over here evaluates to x. Let's say that this thing right over here evaluates toMoreSo this thing right over here evaluates to x. Let's say that this thing right over here evaluates to y so log base b of a is equal to y. And let's say that. This thing over here evaluates to z.

Re-arranging logs into exponential equations - Quick Explanation! YouTube Start of suggested clip End of suggested clip The B lifts the X. Because it just got kicked. The log runs away and the a stays in the same placeMoreThe B lifts the X. Because it just got kicked. The log runs away and the a stays in the same place is equal B to the X. So here let's figure this one out the three is gonna get kicked 9 is gonna stay.

Logs of the same base can be added together by multiplying their arguments: log(xy) = log(x) + log(y). They can be subtracted by dividing the arguments: log(x/y) = log(x) - log(y).
