Answer 1

Applying precedence of operations, the result of the expression is of 161.

What is the precedence of operations?

Power operations are done before multiplication/division, which are also done before addition/subtraction.

Operations inside brackets or parenthesis also take precedence.

In this problem, the operation is:

[3 x 2^5 + 13 x (-2)] + 7[8 - (4 - 9)]

First the power:

[3 x 32 + 13 x (-2)] + 7[8 - (4 - 9)]

Now the multiplications on the first bracket, and the subtraction on the second:

[96 - 26] + 7[8 - (-5)]

Then, applying the parenthesis to the negative number, we have that:

[96 - 26] + 7[8 - (-5)] = 70 + 7 x 13 = 161.

Answer 2

$\huge\text{Hey there!}$

$\mathsf{3 \times 2^5 + 13(-2)] + 7[8 - (4 - 9)]}$

$\mathsf{= 3\times32 + 13\times -2 + 7[8 - (4 - 9)] }$

$\mathsf{= 96 + 13\times -2 + 7(8 - (4 - 9))}$

$\mathsf{= 96 - 26 + 7(8 - (4 - 9))}$

$\mathsf{= 70 + 7(8 - (4 - 9))}$

$\mathsf{= 70 + 7(8 - (-5))}$

$\mathsf{= 70 + 7\times13}$

$\mathsf{= 70 + 91}$

$\mathsf{= 161}$

$\huge\boxed{\frak{161}}\huge\checkmark$
