Apply the multiplier-to-power log rule to move the multipliers 3 and 5 inside their respective logs. Then use the addition rule to combine the first two logs into one. Lastly, apply the subtraction log rule to combine this new log with the third log in the original expression.Write the logarithmic expression 3 log _2 X + log 2_2 Y - 5 log_2 Z as a single logarithm.
