36 throws because you divide 60 by five and get 12 and then multiply 3 by 12 giving you 36, are you sure this is high school
The answer is 17! Hope it helps :)
Following rules of logs, we can do the following:
log x^4 - log y^(1/2) + log z^3
Combine the first and 3rd factors to get log [x^4*z^3]
Seeing that the neg. sign signifies division, write this new term - log y^(1/2) as a quotient:
[x^4*z^3]
log ----------------
y^(1/2)
Next time, please include the instructions when you present your problem.
