`2345 x 25 x 2345 x 74 + 2345`
`= 2345 x ( 25 + 74 + 1 )`
`= 2345 x 100 `
`= 234 500`
2345 x 25 x 2345 x 74 + 2345
= 2345 x ( 25 + 74 + 1 )
= 2345 x 100 = 234 500
2345 x 25 x 2345 x74 +2345
=2345 x 25 x2345 x 74 +2345 x 1
= 2345 x ( 25+74 +1 )
=2345 x 100
=234500
\(=2345\left(7+13+80\right)+7655\left(24+25+51\right)=10000\cdot100=1000000\)
ôi dồi ôi!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
2345 x 25 + 2345 x 74 + 2345 = 2345 x (25+74) = 232155
2345 x 25 + 2345 x 74 + 2345
= 2345 x 25 + 2345 x 74 + 2345 x 1
= 2345 x ( 25 + 74 + 1 )
= 2345 x 100
= 234500
\(\frac{637\times527-189}{526\times637+448}\)
\(=\frac{637\times\left(526+1\right)-189}{526\times637+448}\)
\(=\frac{637\times526+637-189}{526\times637+448}\)
\(=\frac{637\times526+448}{526\times637+448}\)
\(=1\)
\(\frac{677\times874+251}{678\times874-623}\)
\(=\frac{677\times874+251}{\left(677+1\right)\times874-623}\)
\(=\frac{677\times874+251}{677\times874+874-623}\)
\(=\frac{677\times874+251}{677\times874+251}\)

\(x:637=2345\\ x=2345-637\\ x=1708.\)
x : 637 = 2345
x = 2345 x 637
x = 1493765
