\(39\cdot\left(250+87\right)+61\cdot\left(240+97\right)\)
\(=39\cdot337+61\cdot337\)
\(=337\cdot\left(39+61\right)\)
\(=337\cdot100\)
\(=33700\)
39.(250+87)+61.(240+97)
=39.337+61.337
=(39+61).337
=100.337
=33700
Ta có:
39.(250 + 87) + 61.(240 + 97)
= 39 . 337 + 61 . 337
= 337.(39 + 61)
= 337.100
= 33700
\(39.\left(250+87\right)+61.\left(240+97\right)\)
\(=39.337+61.337\)
\(=337.\left(39+61\right)\)
\(=337.100\)
\(=33700\)
\(39\left(250+87\right)+61\left(240+97\right)\)\(=39\left(240+97\right)+61\left(240+97\right)\)\(=\left(61+39\right)\cdot337=100\cdot337\)\(=33700\)
k cho mình nha
39·(250+87)+61·(240+97)
=39·337+61·337
=337·(39+61)
=337·100
=33700
39 x ( 250 + 87 ) + 61 x ( 240 + 97 )
= 39 x 337 + 61 x 337
= ( 39 + 61 ) x 337
= 100 x 337
= 33700
