Solving Log Functions

Solve the logarithmic function:

log₇ (5x - 8) = log₇ (2x + 10)

• x = -3

• x = 6

• x = No solution

• x = 4

Solve the logarithmic function: log₃(x + 5) = 2

• x = 14

• x = 4

• x = 11

• x = 6

Solve the logarithmic function: 4 + log₃(x - 7) = 6

• x = 34

• x = 16

• x = 2

• x = 72

-4+log₃(x + 27) = 1

• x = 27

• x = 243

• x = 216

• x = 359

log₅(3x + 3) = log₅(2x + 8)

• x = -4

• x = 5

• x = 1

• x= No solution

log₅ x - log₅6= 2

• x = 150

• x = 256

• x = 315

• x = 205

log₄2 + log₄x = 3

• x = 64
• x = 32
• x = 21
• x = 4

Rewrite 3⁴ = 81 in logarithmic form.

• log₃4 = 81
