To solve this equation, we first calculate the values inside the brackets:1. For the first part of the equation: 1/(2*3.19*64.516*10^6*10^-14) = 0.00001525882. For the second part of the equation: 1/(25*10^3) + 1/(15*10^3) = 0.00004 + 0.0000666667 = 0.0000666667Then, we multiply these two results together: 0.0000152588 * 0.0000666667 = 0.000000001014. So, the answer is 0.000000001014.

This is a mathematical computation question. The question requires the application of basic arithmetic operations and the knowledge of the order of operations (BIDMAS/BODMAS - Brackets, Indices/Orders, Division and Multiplication (from left to right), Addition and Subtraction (from left to right)). First, we need to calculate the values inside the brackets. The first part of the equation is a division operation, where 1 is divided by the product of 2, 3.19, 64.516, 10^6 and 10^-14. The second part of the equation is an addition operation, where 1/25*10^3 is added to 1/15*10^3. After calculating these two parts, we multiply them together to get the final answer. It's important to remember that in mathematics, the order of operations must be followed to ensure accurate results. This means that any calculations inside brackets must be done first, followed by any exponentiation, then multiplication and division (from left to right), and finally addition and subtraction (from left to right).
