k mik nhé
\(66\cdot25+5\cdot66+66\cdot14+33\cdot66\)
\(=66(25+5+14+33)\)
\(=66\cdot77\)
\(=5082\)
66.25+5.66+66.14+33.66=66. (25+5+14+33)
=66. 77
=5082
66. 25 + 5 . 66 + 66 . 14 + 33 . 66
=66.(25+5+14+33)
=66.77
=5082
\(66.25+5.66+66.14+33.66\)
\(=66\left(25+5+14+33\right)\)
\(=66.77\)
\(=5082\)
66.25+5.66+66.14+33.66
=66.(25+5+14+33)
=66.77
