• 6log₈(xyz)
• log₈(x) - log₈(y) - 6log₈(z)
• log₈(x) + log₈(y) - log₈(z)
• log₈(x) + log₈(y) + 6log₈(z)

Match each exponential expression to its equivalent logarithmic form.

• e^x ≈ 10

• ln x ≈ 10

• 3^x = 10

• log_x 3 = 10

• x¹⁰ = 3

• log x = 3

• 10³ = x

• ln 10 ≈ x

• e¹⁰ ≈ x

• log₃ 10 = x
