Question

Rut gon bt P=12(5^2+1)(5^4+1)(5^8+1)(5^16+1)

 

Answer 1

P=2.(5^2-1).(5^2+1).(5^4+1).(5^8+1).(5^16+1)

 =2.(5^4-1).(5^4+1).(5^8+1).(5^16+1)

= 2.(5^8-1).(5^8+1).(5^16+1)

= 2.(5^16-1).(5^16+1)

= 2.(5^32-1)

Answer 2

 1)P= 12(5^2+1)(5^4+1)(5^8+1)(5^16+1) 
=> 2P = 24(5^2+1)(5^4+1)(5^8+1)(5^16+1) 
=(5^2-1)(5^2+1)(5^4+1)(5^8+1)(5^16+1) 
=(5^4-1)(5^4+1)(5^8+1)(5^16+1) 
=(5^8-1)(5^8+1)(5^16+1) 
=(5^16-1)(5^16+1) 
=5^32-1 
=> P = (5^32-1)/2
