Write as a single log:
 log 12 + 2 log x

• log (12 + 2x)
• log (14x)
• log (12 * 2x)
• log (12x²)

Solve:
_{log (4x − 5) = log (2x − 1)} 

• 0
• 1
• 2
• 3

log (x) + log (x) = log (25)

• log (4g/2h)
• log (g⁴/h²)
• log (g⁴ - h²)
• log (2gh)

Expand:  log(uv⁴)⁴

• 4log₄u - 16log₄v
• 4logu + 16logv
• 4logu - 4logv
• 4logu - 16logv
