A calculator has a key for squaring and another key for inverting, so if x is a displayed number, then pressing the square key will replace the x by x^2 and pressing the inverse key replace it by 1/x. if initially the number displayed is 6 and one alternately presses invert key and square key 16 times each, then the final number displayed will be

• the power is increased in 2,4,8,16....so the answer is 6^(6^216)= 6^65536

• 1st inverse and then square. At 16th time 6^32

• 6^(2^16)
  
  The power of 6 gets increased in the order 2,4,6,8 in even pressings (ie squaring)
  so at the 16TH press the power would be 2^16
  and so the answer is
  6^(2^16)

• ans is 6^65536

• 16th term:power of 6 is 2^16
• 10 years agoHelpfull: Yes(4) No(3)
• 6 ki power (2^16)

• Eqn will be of the form (1/6)^2 ,(6)^4,(1/6)^8......upto 16th term
  
  if we luk at the powers carefully... they are in GP thus power to the 16th term would be 2(2^15)=2^16 hence the no displayed will be 6 raised to the power 2^16

• can anyone explain the sol clearly?

• the series will be 1/6,(1/6)^2,(6)^2,(6)^4.......
  consider 1/6,(1/6)^2 as asingle term and so on then even term is not inverted.
  so 16th term is not inverted.
  so,16th term is 6. and power of 6 is 2*16=32.
  so,answer is 6^32.

• sorry my mistake power of 6 would be 2^15...
• 10 years agoHelpfull: Yes(0) No(3)
• is it 36^15..
• 10 years agoHelpfull: Yes(0) No(0)
• answer is 6^288
• 10 years agoHelpfull: Yes(0) No(0)
• 6^32 bcz at even times it becomes 6^(no. of times key pressed*2)
• 10 years agoHelpfull: Yes(0) No(2)
• can anyone explain the correct answer
• 10 years agoHelpfull: Yes(0) No(0)
• guys the answere is 6^8192,,,,since it is said that we have to invert and then square it for 16 times each,,,,,each is mentioned there
