Question

How do you solve this logarithmic equation? 3x-5=log(down arrow)2 1024

2 Answer

  • What does down arrow mean
  • 3x -5 = log base2 1024
    Log base 2 1024 can be rewritten log (base 2) 2^10
    log (base 2) 2^10 =
    10 * log (base 2) 2
    log (base 2) 2 = 1
    So 10 * log (base 2) 2 = 10
    3x -5 = 10
    Add 5 to both sides
    3x = 15
    Divide both sides by 3
    x = 5
