Answer 2

To solve this expression, 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).

1. First, calculate the values within the parentheses:

   3 1/9 + 8/9 = (28/9) + (8/9) = (28 + 8)/9 = 36/9 = 4

2. Now, square the result from step 1:

   4² = 16

3. Next, calculate the squares of 1.6 and 0.7:

   1.6² = 2.56 0.7² = 0.49

4. Add the squares from step 3 to the result from step 2:

   16 + 2.56 + 0.49 = 18.05

So, the result of the expression is approximately 18.05.
