A denotes the product xyz where x, y, z satisfy

Log3x=log5-log7

Log5y=log7-log3

Log7z=log3-log5

Find A??

5 If            4813532 = ba  where a and b are natural number find (a + b).
  • 0
Log3x=log5-log7
=> log x = log35 / log 7 ( changing base rule)
=> x = 5/7
similarly
 y= 7/3 
 z= 3/5
 A = 5*7*3/(7*3*5)
xyz=A = 1
