Solving Exp and Log Equations

Solve for x:  log₆x + log₆(x-5) = 2

• √7
• 9
• 4
• none of these

Solve the following for 'x';

log₆(3x - 2) = log₆(5x - 8)

• x = 3

• x = 2

• x = -1

• No Solution

Determine the correct set-up for:

log₄(x-1) - log₄(x+7) = log₄6

• log₄(x-1)/(x+7)=log₄(6)

• log₄(x-1)(x+7)=log₄(6)

• log₄(x+7)/(x-1)=log₄(6)

• (x-1)(x+7)=6

Solve:

log₉(-5x) - log₉(6)=1

• 4.50

• 53.33

• -10.800

• 13.50

The first step to solve 8 + log 7 = 10 is...

• Rewrite exponentially

• Subtract 8 on both sides to isolate the log

• Divide by 7 on both sides

Solve:

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

• 152.68

• 188.77

• 4.24

• 8.01

Solve:

log₈(6-5x) = log₈(3- 4x)

• x = 3

• No Solution

• x = 9

• x = 1

Which is the correct way to rewrite,log₆(x-3)= 2, in order to solve.

• 6² = x-3

• 2⁶ = x - 3

• ln(2) = x-3

• e⁶ = x-3

Solve:

2log₆(x-8)=2

• 14

• 81/8

• 18

• 9969

Solve:

log₂(x + 3)=5

• x=2

• x=29

• x=7

• x=32
