Answer:
see below
Step-by-step explanation:
what 3 logy z^9 means you need to break it into two pieces, one log y z^9 means to find the exponent of y, and you can think z^9 as a number, and then if we multiple it with 3, which means three logs are summed,(the property of multiplication:3*2 means 2+2+2), thus log + log
has the property that the y is same z^9*z^9*z^9=z^(9+9+9)=z^27
