Ta có:
10.3+10.4+10.3=10.(3+4+3)=10.10=100
Vậy =100
\(10.3+10.4+10.3\)
\(=10\left(3+4+3\right)\)
\(=10.10\)
\(=10^2=100\)
~~~!!!
\(10.3+10.4+10.3\)
\(=10\left(3+4+3\right)\)
\(=10.10=10^2\)
\(=100\)
\(10.3+10.4+10.3\)
\(=10.\left(3+4+3\right)\)
\(=10.10\)
\(=100\)
Cách 1 :
10.3 + 10.4 +10.3
= 30 + 40 + 30
= 100
Cách 2 :
10.3 + 10.4 + 10.3
= 10. ( 3 + 4 + 3 )
= 10 . 10
= 100
10.3 + 10.4 + 10.3
= 10 . ( 3 + 4 + 3 )
= 10 . 10
= 100
# vanh #
cách 1 :30+40+30=70+30=100
cách 2 :10*(3+4+3)=10*10=100
dấu(*)la nhân
\(10\cdot3+10\cdot4+10\cdot3\)
\(=10\cdot\left(3+4+3\right)\)
\(=10\cdot10\)
\(=100\)
\(10.3+10.4+10.3\)
\(=30+40+30\)
\(=70+30\)
\(=100\)
Chúc bạn học tốt!
Thân!
10 . 3 + 10 . 4 + 10 . 3
= 10 . (3 + 4 + 3)
= 10 . 10
= 100
