Question

5+{2[(48-40)÷4+(2×5)]}

Answer 1

The given expression is

`5+\left\{ 2\left[\left(48-40\right)/4+\left(2*5\right)\right]\right\} ​`

First, we solve parenthesis, the operation inside of them

`5+\left\{ 2\left[8/4+10\right]\right\} ​`

Second, we solve brackets

`5+\left\{ 2\left[2+10\right]\right\} ​\rightarrow5+\left\{ 2\left[12\right]\right\} \rightarrow5+\left\lbrace 24\right\rbrace \rightarrow5+24`

Finally, we sum

`29`

Therefore, the answer is 29.
