**Use a Calculator (or Phone App) to Evaluate a Mathematical Expression** ===========================================================

What is the Expression We Need to Evaluate?

The expression we need to evaluate is $2(7-3)^2 \div 8$. This expression involves several mathematical operations, including subtraction, exponentiation, multiplication, and division.

Step 1: Evaluate the Expression Inside the Parentheses

The first step is to evaluate the expression inside the parentheses, which is $7-3$. This is a simple subtraction problem, and the result is $4$.

(7-3) = 4

Step 2: Raise 4 to the Power of 2

Next, we need to raise 4 to the power of 2, which is denoted by $4^2$. This is a simple exponentiation problem, and the result is $16$.

4^2 = 16

Step 3: Multiply 2 by 16

Now, we need to multiply 2 by 16, which is a simple multiplication problem. The result is $32$.

2 \times 16 = 32

Step 4: Divide 32 by 8

Finally, we need to divide 32 by 8, which is a simple division problem. The result is $4$.

32 \div 8 = 4

Conclusion

Therefore, the final answer to the expression $2(7-3)^2 \div 8$ is $4$.
