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)
rút gọn: 12.(5^2 + 1).(5^4 + 1).(5^8 + 1).(5^16 + 1)
bài 1
(4^2+1)(4^4+1)(4^8+1)(4^16+1)(4^32+1)-1/15*4^64
Bài 2:Cho x+1/x=10. Tính S=x^5+1/x^5
Rút gọn biểu thức
P= 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)
Cho P=12*(5^2+1)(5^4=1)(5^8+1)(5^16+1). Tính P.
Rút gọn nhanh Q=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)
