Trả lời
74.26+26.25+99.74
=26.(74+25)+99.74
=26.99.99+74
=99.(26+74)
=99.100
=9900
\(74\times26+26\times25+99\times74\)
\(=26\left(74+25\right)+99\times74\)
\(=26\times99+99\times74\)
\(=99\times\left(26+74\right)\)
\(=99\times100\)
\(=9900\)
74x26+26x25+99x74
=26x(74+25)+99x74
=26x99+99x74
=99x(26+74)
=99x100
=9900
= 26 .( 74 + 25 ) + 99 .74
=26. 99 + 99 .74
= 99 . ( 74 + 26 )
= 99 . 100
= 9900
=26.(74+25)+99.74
=26.99+99.74
=99.(26+74)
=99.100
=9900
74.26+26.25+99.74
=26.(74+25)+99.74
=26.99+99.74
=99.(26+74)
=99.100
=9900
