Logs again..

  • 1 vote

Yet again, logs are confusing me. I really need help understanding these questions:

  1. Solve 5^x = 2^x-1 to three sig. figs.
  2. Given that p = 8^1/2 and q =4^3/2,
  • express p as powers of 2
  • express q as powers of 2
  • express pq as a power of 2

Any help, no matter how little, will be much appreciated!
