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

• log₂(x/y⁵)

• log₂(xy⁵)

• log₂(x/y)⁵

• log₂(x/5y)

• log (xy³)
• log (x⁶ − y³)
• log (x⁶/y³)
• log (x⁶ + y³)

Rewrite each logarithmic equation as an exponential equation and vise versa

Match each logarithmic expression to its equivalent exponential form.

• e^x ≈ 10

• log₅ 10 = x

• x¹⁰ = 5

• ln x ≈ 10

• 10⁵ = x

• ln 10 ≈ x

• e¹⁰ ≈ x

• log_x 5 = 10

• 5^x = 10

• log x = 5
