Question

The expression  where p greater or equal than 2 comma p element of N semicolon n element of Nwhen  simplified is.

  1. Independent of p    
  2. Independent of p and of n    
  3. dependent on both p & n    
  4. positive    

hintHint:

Using formula left parenthesis a to the power of x right parenthesis to the power of y space equals space a to the power of x y end exponent , log subscript a open parentheses b to the power of c close parentheses space equals space c space log subscript a open parentheses b close parentheses right square bracket and log subscript a open parentheses a close parentheses space equals space 1 find the value of given expression in terms of n and p 's .

The correct answer is: Independent of p


     = log subscript p open parentheses p to the power of 1 over p x 1 over p x 1 over p x.... space n space t i m e s end exponent close parentheses space
    equals space log subscript p open parentheses p to the power of n over p end exponent close parentheses space space left square bracket u sin g comma space log subscript a open parentheses b to the power of c close parentheses space equals space c space log subscript a open parentheses b close parentheses right square bracket
equals n over p space log subscript p open parentheses p close parentheses space left square bracket space u sin g comma space log subscript a open parentheses a close parentheses space equals 1 right square bracket
equals space n over p
    Therefore, the value of expression is  dependent on both n and p.
