k đúng cho mình nha.
a,64+469+31+36
=(64+36)+(496+36)
=100+500
=600
b,25.2018.4
=25.4.2018
= 100.2018
= 201800
c,325.78+325.22
= 325.(78+22)
= 325.100
32500
\(a,64+469+31+36\)
\(=\left(64+36\right)+\left(469+31\right)\)
\(=100+500\)
\(=600\)
\(b,25.2018.4\)
\(=25.4.2018\)
\(=100.2018\)
\(=201800\)
\(c,325.78+325.22\)
\(=325.\left(78+22\right)\)
\(=325.100\)
