\(10\cdot5+10\cdot5+10\cdot3=10\cdot\left(5+5+3\right)=10\cdot13=130\)
10.5+10.5+10.3
=10. (5+5+3)
=10.13
= 130
k mình nha mình đầu tiên nè
10 . 5 + 10 . 5 + 10 . 3
= 10 . ( 5 + 5 + 3 )
= 10 . 13
= 130
10.5 + 10.5 + 10.3
=10. [5 + 5 + 3]
=10.13
130
10.5+10.5+10.3=10.(5+5+3)=10.13=130
\(10\cdot5+10\cdot5+10\cdot3=10\cdot\left(5+5+3\right)=10\cdot13=130\)
10.5+10.5+10.3
=10*5+10*5+10*3
=50+50+30
=130
