Answer 2

\(7,2\times5+3,6\times6+7,2\times2\\ =7,2\times5+7,2\times3+7,2\times2\\ =7,2\times\left(5+2+3\right)\\ =7,2\times10\\ =72\)

Answer 3

`7,2xx5+3,6xx6+7,2xx2`

`=7,2xx5+3,6xx2xx3+7,2xx2`

`=7,2xx5+7,2xx3+7,2xx2`

`=7,2xx(5+3+2)`

`=7,2xx10`

`=72`

Answer 4

\(7,2\cdot5+3,6\cdot6+7,2\cdot2\)

\(=7,2\cdot5+7,2\cdot3+7,2\cdot2\)

\(=7,2\left(5+3+2\right)\)

= \(7,2\cdot10=72\)
