Hey, im doing work on logarithms but these two kinds of q's have puzzled me could you plase tell me what the process to solving these type f q's is.

how do i work out how to express these type of terms in log x ,logx^5-2logx.

also for these type of logarithms to the base of 10 to solve these equations, 0.99^x=0.000001

Thank you
