Question

Please help!
write the expression log √10xy^2/z^2 as a combination of log x, log y, and log Z. That means break it up completely.

Answer 1

Is that log base 10? Is the argument in the squareroot 10 or 10xy^2/z^2?
Remember that you can raise square roots signs as powers and log_10 sqrt(a) = log_10 a^0.5 = 0.5*log_10 a
