P= 12.(52+1)(54 +1)(58+1)(516+1)
=>2P=24.(52+1)(54 +1)(58+1)(516+1)
=(52 -1)(52+1)(54+1)(58+1)(516+1)
=(58- 1)(58+1)(516+1)
=(516 -1)(516 -1)
= 532 -1
Cho M =12.(5^2 + 1)(5^4+1)(5^8+1)(5^16+1)(5^32+1)
Và N=5^64.Tính 2.M_N
Rút gọn biểu thức:
12.(52+1). (54+1). (58+1).(516+1)12.(52+1). (54+1). (58+1).(516+1)
P=12(5^2 +1)(5^4+1)(5^8+1)(5^16+1)
Tính:12 . (5^2 + 1) . (5^4 +1) . (5^8 +1) . (5^16 + 1)
rút gọn: 12.(5^2 + 1).(5^4 + 1).(5^8 + 1).(5^16 + 1)
rút gon: C=12(5^2+1)(5^4+1)(5^8+1)(5^16+1)
Rút gọn nhanh Q=12(5^2 + 1)(5^4 + 1)(5^8 + 1)(5^16 + 1)
Rút gọn biểu thức
P= 12(5^2+1)(5^4+1)(5^8+1)(5^16+1)
Rút gọn 12(5^2+1)(5^4+1)(5^8+1)(5^16+1)
