Simplify: 3log(xy) - 2log(x)

• log(xy³)
• log(y)
• 1.5log(x²y)
• Can't be simplified

What is the most simple answer possible:
log_x(x³y) - log_x(xy)

• log_x(x²)
• 2
• log_x(x⁴-y²)
• x

Expand the following logarithm: 
log₂ 5x.

• log₂ 5 - log₂ x 
• log₂ 5 + log₂ x 
• 2log 5 + 2log x
• log5 2 + log_x 2
