Solving Log Equations by Condensing

Front

Write log_b(x/y) as two logs

Back

log_bx-log_by

Front

Use multiple log properties to write as a sum or difference of two logs: log(4x³)

Back

log 4 + 3log x

Front

Use multiple log properties to write as a single log:
log₂x -  5log₂y

Back

log₂(x/y⁵)

Front

Solve for x:  log₆x + log₆(x-5) = 2

Back

9

Front

log (x - 1) - log (x - 2) = log 5

Back

9/4

Front

ln(x+8) - ln (8) = 3

Back

152.68

Front

log₉(10)-log₉(x-3) =log₉(72)

Back

113/36

Front

log₉(x)+log₉(x+2)=log₉(35)

Back

5

Front

log₅x - log₅(x+4)=log₅38

Back

No Solution

Front

log7+log(x²-4)=log35

Back
