\(24.17+52.76+24.35\)
\(=24.\left(17+35\right)+52.76\)
\(=24.52+52.76\)
\(=52.\left(76+24\right)\)
\(=52.100\)
\(=5200\)
24 x 17 + 52 x 76 + 24 x 35
= 24 x ( 17 + 35 ) + 52 x 76
= 24 x 52 + 52 x 76
= 52 x ( 24 + 76 )
= 52 x 100
= 5200

24 x 17 + 52 x 76 + 24 x 35
=24 x 17 + 52 x 3 x 24 + 24 x 35
=24 x 17 + 156 x 24 + 24 x 35
=24 x (17 + 156 + 35)
=24 x 208
=4932
đó là cách nhanh nhất
\(24\times17+52\times76+24\times35\)
\(=24\times\left(17+35\right)+52\times76\)
\(=24\times52+52\times76\)
\(=52\times\left(24+76\right)\)
\(=52\times100\)
\(=5200\)
