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

• 152.68

• 188.77

• 4.24

• 8.01

Solve:

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

• 7

• 4/9

• 9/4

• 1/7

log₉(x)+log₉(x+2)=log₉(35)

• 5

• -7

• 5, -7

• -7, -13

log7+log(x²-4)=log35

• -1

• -2

• -3

• -4

Solve log₉ (x - 4) + log₉ (x + 1) = log₉ (x + 5) + log₉ (x - 6)

• 17/2

• -9/16

• 13

• -8

• ln2+2lnx+lny+4lnz

• ln2+2lnx+lny-4lnz

• 2ln(2xy)-4lnz

• 2ln2x+lny-4lnz

Solve for x:  log₆x + log₆(x-5) = 2

• √7

• 9

• 4

• none of these

log₉(10)-log₉(x-3) =log₉(72)

• 81/16

• 113/36

• No Solution
