\(136\cdot48+16\cdot272+68\cdot20\cdot2\)

\(=136\cdot48+16\cdot2\cdot136+136\cdot20\)

\(=136\cdot48+136\cdot32+136\cdot20\)

\(=136\cdot\left(48+32+20\right)\)

\(=136\cdot100\)

\(=13600\)

= 136 . 48 + 16 . 272 + 68 . 2 . 20

= 136 . 48 + 16 . 272 + 136 . 20

= 136 . (48 + 20) + 16 . 272

= 136 . 68 + 16 . 272

= 136 . 2 . 34 + 16 . 272

= 272 . 34 + 16 . 272

= 272 . (34 + 16)

= 272 . 50

= 13600
