Question

Evaluate 5+{2[(48-40)/4+(2*5)]}

Answer 1

Given:-

$5+2\lbrack\frac{(48-40)}{4}+(2\times5)\rbrack$

At first simplify the brackerts,

$5+2\lbrack\frac{(48-40)}{4}+(2\times5)\rbrack=5+2\lbrack\frac{8}{4}+10\rbrack$

Now simplify the division,

$5+2\lbrack\frac{8}{4}+10\rbrack=5+2\lbrack2+10\rbrack$

Now solve the bracket,

$\begin{gathered} 5+2\lbrack2+10\rbrack=5+2(12) \\ \text{ =5+24} \\ \text{ =29} \end{gathered}$

The solution is 29.
