Answer 2

To calculate the expression you provided, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Here's how you can calculate the expression step by step:

1. Calculate the values within the parentheses:

   • $25^2 = 625$
   • $79.75^2 \approx 6360.0625$
   • $0.4^2 = 0.16$
   • $1.6^2 = 2.56$

2. Calculate the division and addition within the parentheses:

   • $6360.0625 - 625 = 5735.0625$
   • $0.16 + 2.56 = 2.72$

3. Finally, perform the division and addition/subtraction from left to right:

   • $\frac{5735.0625}{2.72 + 1.28} = \frac{5735.0625}{4} \approx 1433.765625$

So, the result of the expression is approximately $1433.77$ (rounded to two decimal places).
