39*57+53*172-53*84=2223+53*[172-84]
=2223+53*88
=2223+4664
=6887
39 x 57 = 2223
53 x 172 = 9116
53 x 84 = 4452
2223 + 9116 - 4452 = 6887
39 x 57 + 53 x 172 - 53 x 84 = 53 x (172 - 84) + (39 x 57)
= 53 x 88 + 39 x 57
= 4664 + 2223
= 6887
\(39\cdot57+53\cdot127-53\cdot84\)
\(=2223+53\cdot\left[172-84\right]\)
\(=2223+53\cdot88\)
\(=2223+4664\)
\(=6887\)
39 x 57 + 53 x 172 - 53 x 84
= 39 x 57 + 53 x ( 172-84)
= 39 x57 + 53 x 88
= 2223 + 4664
