Answer:

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.
