Question

The value of 3 to the power of log subscript 4 end subscript invisible function application 5 end exponent minus 5 to the power of log subscript 4 end subscript invisible function application 3 end exponent is

  1. 0  
  2. 1  
  3. 2  
  4. None of these  

The correct answer is: 0


    Let 3 to the power of log subscript 4 end subscript invisible function application 5 end exponent equals a rightwards double arrow log subscript 4 end subscript invisible function application 5 equals l o g subscript 3 end subscript a rightwards double arrow fraction numerator log invisible function application 5 over denominator l o g blank 4 end fraction equals fraction numerator log invisible function application a over denominator log invisible function application 3 end fraction
    rightwards double arrow fraction numerator log invisible function application a over denominator log invisible function application 5 end fraction equals fraction numerator log invisible function application 3 over denominator log invisible function application 4 end fraction rightwards double arrow log subscript 5 end subscript invisible function application a equals log subscript 4 end subscript invisible function application 3
    rightwards double arrow a equals 5 to the power of log subscript 4 end subscript invisible function application 3 end exponent rightwards double arrow 3 to the power of log subscript 4 end subscript invisible function application 5 end exponent minus 5 to the power of log subscript 4 end subscript invisible function application 3 end exponent equals 0
