B=11!
B=39916800
39916800>500500
B>A

39916800>500500
B>A
so sanh A va B; A=1/2^2+1/2^3+.....+1/2^1000; B=1
so sanh A va B; A=1/2+1/2^2+1/2^3+.....+1/2^1000; B=1
so sanh a
a) 9 mu 20 va 27 mu 13
b) 3 mu 1000 va 2 mu 1500
Cho A = 1 + 2 + 2^2 + 2 ^ 3 + ... + 2 ^2017
va B -= 2^2018 - 1
So sanh A va B
giai ra giu mk nha
SO SANH 2 So sau
a, 2^10 va 8^4
b 3^2n va 2^3n n E N
c 2^105 va 5^45
TICK NHE AI NHANh
a) tim so tu nhien nho nhat biet rang so do chia het cho 9 du 5, chia cho 7 du 4 va chia cho 5 thi du 3
b) cho A = 1+2017+20172+20173+20174+. . .+201771+201772 va B = 201773-1. So sanh A va B.
c) tim hai so tu nhien a va b, biet : BCNN (a, b) = 300 , UCLN (a, b) = 15 va a+15 = b.
Giup minh giai di nha. Cam on may ban nha
So sanh A va B.
A=4.8.12 +8.12.16 +12.16.20 +16.20.24
B=1.2.3+ 2.3.4 +3.4.5 +4.5.6
So sanh A va B.
A=4.8.12 +8.12.16 +12.16.20 +16.20.24
B=1.2.3+ 2.3.4 +3.4.5 +4.5.6
Bai 1 : So sanh :
a ) - 23 / -17 va -13 / -17
b ) -57 / 53 va -97 / 93
c ) -21 / 29 va 81 / -89
