See a solution process below:

First, execute the Exponent operation:

$(7 + 2^{3}) \times 9 \Rightarrow (7 + 8) \times 9$ $(7 + color(red)(2^3)) xx 9 => (7 + 8) xx 9$

Next, execute the Addition operation within the Parenthesis:

$(7 + 8) \times 9 \Rightarrow 15 \times 9$ $(color(red)(7) + color(red)(8)) xx 9 => 15 xx 9$

Now, execute the Multiplication operation:

$15 \times 9 \Rightarrow 135$ $15 xx 9 => 135$
