Question

The expression was rewritten using the ( blank?)
i’m so confused pls help

Answer 1

I am solving the equation in simplest way

Line:-1

`\\ \tt\bull\longmapsto 9.(7+1)`

• Solve the bracket

`\\ \tt\bull\longmapsto 9(8)`

`\\ \tt\bull\longmapsto 72`

Line:-2

`\\ \tt\bull\longmapsto 9.7+9.1`

`\\ \tt\bull\longmapsto 63+9`

`\\ \tt\bull\longmapsto 72`

Answer 2

It was solved using distributive property

Explanation:

`{ \tt{9•(7 + 1)}}`

• 9 outside the bracket is distributed to each value in the bracket:

`= { \tt{(9•7 + 9•1)}} \\ \\ = { \tt{63 + 9}} \\ \\ { \tt{ = 72}}`
