Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) and work from left to right. Let's break it down step by step:

1. First, perform the multiplication and division from left to right:

   3 × 10^(-7) × 0.5 × 7200 / 8800 × 0.0096

   = (3 × 10^(-7)) × 0.5 × 7200 / 8800 × 0.0096

   = (3 × 0.5) × 7200 / 8800 × 0.0096

   = 1.5 × 7200 / 8800 × 0.0096

2. Now, perform the remaining multiplications and divisions from left to right:

   = (1.5 × 7200) / 8800 × 0.0096

   = 10800 / 8800 × 0.0096

3. Finally, perform the last multiplication and division:

   = (10800 / 8800) × 0.0096

Now, calculate the values inside the parentheses:

= 1.22727272727 × 0.0096

= 0.01178181818

So, 3×10^(-7)×0.5×7200/8800×0.0096 is approximately equal to 0.01178181818.
