If A^B means A raised to the power of B, in which of the following choices must P be greater than Q
a) 0.9^P=0.9^Q
b) 0.9^P=0.92^Q
c) 0.9^P>0.9^q

• ans b.
  
  if we take p>q, then we directly eliminate option a.
  
  0.9 is a decimal number, so higher power of 0.9 will be smaller number.
  hence option c will be eliminated.
  
  obviously option b will be the answer

• Ans- c as 0.9 is base on both side.
  P>Q
• 9 years agoHelpfull: Yes(2) No(4)
• none of the above mentioned option satisfies the condition
• 9 years agoHelpfull: Yes(1) No(0)
• for power
• 9 years agoHelpfull: Yes(1) No(0)
• check by option simply put the value pas 10 and q as 9.
• 9 years agoHelpfull: Yes(1) No(0)
• none of the above options satisfied the condition
• 9 years agoHelpfull: Yes(1) No(0)
• b) 0.9^p=0.9^Q
  
• 9 years agoHelpfull: Yes(0) No(0)
• Option A is wrong as P = Q
  Option B is wrong as P/Q=Log0.92/Log0.9=0.79139
  Option C is also wrong as aP>aQ then P>Q if a > 1
• 9 years agoHelpfull: Yes(0) No(0)
• all options are not satisfied.
  if the option is like that 0.9P>0.9Q then it will be satisfied.
