Assume that x, y and z are positive numbers. Use the properties of logarithms to write the expression -2logb^(x-6)logb^y+1/7logb^z as the logarithm of one quantity. answers: a. logb z1/7 / x^2y^6 b. logb z 1/7 / x^6y^2 c. log x1/7 / y^2 z^6 d. logb z1/2 /...

do you know where I made the error or can you help me with the answer?

I'm still struggling to figure out the answer though. Ms. Sue can you help me?

I have this same question. I've looked at the link too and can't figure it out. Miriam what did you get?
