To determine

The solution of the given expression.

Answer to Problem 1.2.30EP

  $169$

Explanation of Solution

Given:

The given statement is:

  ${\left[a+8\left(b-2\right)\right]}^2÷4$

  $\begin{array}{l}a=2\\ b=5\\ x=4\\ n=10\end{array}$

Calculation:

The equation can be written as:

  $\begin{array}{l}={\left[a+8\left(b-2\right)\right]}^2÷4\\ ={\left[2+8\left(5-2\right)\right]}^2÷4\\ ={\left[2+8\left(3\right)\right]}^2÷4\\ ={\left[26\right]}^2÷4\\ =\frac{26\left(26\right)}{4}\\ =169\end{array}$
