Answer 2

The answer is
`{\underline{\boxed{\sf{\purple{4}}}}}`

Step-by-step explanation:

Solution :

To solve the above equation we will follow the BODMAS rule.

• 
  `\small\pink\bull` BODMAS is an order of mathematic operations.
• 
  `\small\pink\bull` BODMAS rule is to be followed while solving expressions in mathematics.

It stands for :

`\begin{gathered}\quad\begin{gathered} \small \begin{array}{l} \star \: \rm B= bracket \\\star \: \rm O= order \: of \: power \: \\\star \: \rm D= division \\\star \: \rm M= multiplication \\ \star \: \rm A= addition \\ \star \: \rm S=subtraction \end{array}\end{gathered}\end{gathered}`

Solving the question by bodmas rule :

`\implies\tt{\frac{15 - 7 + 3(6 + 2)}{{2}^(3)}}`

`\implies\tt{(15 - 7 + 3(8))/(2 * 2 * 2)}`

`\implies\tt{(15 - 7 + 3 * 8)/(4* 2)}`

`\implies\tt{(15 - 7 + 24)/(8)}`

`\implies\tt{(39- 7)/(8)}`

`\implies\tt{(32)/(8)}`

`\implies\tt{\cancel{(32)/(8)}}`

`\implies\tt{\underline{\underline{\red{4}}}}`

Hence, the answer is 4.
