Let's break down the expression shown in the image step by step:

The expression is:

$13 - \left( 6.5 - \left| -\frac{3}{4} \right| \right) \times (-3)^2 - 9 \times \frac{1}{4}$

Step-by-Step Solution:

1. Evaluate the absolute value: $\left| -\frac{3}{4} \right| = \frac{3}{4}$ So the expression becomes: [ 13 - \left( 6.
