Question 2023
1)log9 49 - log9 7 + log9 5
 = log9 (49/7) + log9 5
 = log9 7 + log9 5
 =  log9 35

2) 2log8 6 - log8 4
  = log8 6^2 - log8 4
  = log8 36 - log8 4
  = log8 36/4
  = log8 9


3) 4log8 3 - 2log8 2
  = log8 3^4 - log8 2^2
  = log8 81 - log8 4
  = log8 81/4
  = log8 20.25

4) log2 225 - log2 5 + log2 3
   = log2 (225/5)+ log2 3
   = log2 45+ log2 3
   = log2 135
5) 5log37 37^9
  = 5(9 log37 37)
  = 5*9*1
  = 45

 You have to work hard.
