k mk nha!!!
a) 397+512 = 909
b) 34x 2002 = 68068
c) 24 x25 x26 = 15600
d)999 x 202 = 201798
\(a,397+512=909\)
\(b,34\cdot2002=68068\)
\(c,24\cdot25\cdot26=15600\)
\(d,999\cdot202=201798\)
Hok tốt
a)397+512=909
b)34 \(\times\)2002=68068
c) 24\(\times\)25\(\times\)26 = 15600
d) 999\(\times\)202 = 201978
