cach lam cau hoi so sanh 2 so 88^99 va 99^88
so sanh
5^333va 3^555
cu the cach lam tick cho
so sanh A= 1/2^2 + 1/ 3^2 +1/4^2+...+ 1/300^2 voi 3/4
so sanh A va B voi 0
A = 1. ( - 2 ) . 3 . ( - 4 ) ..... . 99 . ( -100 )
B = 1 . ( - 2 ) . 3 . ( - 4 ) . ... . (-98) . 99
So sanh A va B
A=(1+3+5+.......+99) / 50
B=( 2+4+6+.....+98)/ 49
C=98^99+1/98^89+1 va D=98^98+1/98^88+1. So sanh C va D
C=98^99+1/98^89+1 va D=98^98+1/98^88+1. So sanh C va D
SO SANH
A=\(\frac{1}{4^2}+\frac{1}{6^2}+........+\frac{1}{2018^2}\) với 99
