a, 435*25+76*435-435
=435*(25+76-1)
=435*100
=43500
b, 35*49+51*36
=35*49+51*(35+1)
=35*49+51*35+51
=35*(49+51)+51
=35*100+51
=3500+51
=3551
\(a,435\times25+76\times435-435\)
\(=435\times\left(25+76-1\right)\)
\(=435\times100\)
\(=43500\)
\(b,35\times49+51\times36\)
\(=1715+1836\)
\(=3551\)
a) 435.25+76.435-435 b) 35.49+51.36
=435(25+76-1) =?????
=435.100 ý b có sai đầu bài k đó bn ơi????
=43500
=435×(435-435)×(25+76)
=435×0×(25+76)
=0×25+76
=0+76
=76
a] 435 * 25 + 76 * 435 - 435 b] 35 * 49 + 51 * 36
= 10875 + 33060 - 435 = 1715 + 1836
= 43935 - 435 = 3551
= 43500
