Answer 1

firstly, do you know the log properities?

Answer 2

Uhh like log 125^9x-2 = log150

Answer 3

if you take the log of a^b what happens?

Answer 4

(9x-2)log125=log150

Answer 5

the b comes down and multiplies with the rest. i.e. you will get b*log(a)

Answer 6

ok what do you think you should be next?

Answer 7

Uhh... (9x)log125 - (2)log125 = log 150 ?
