Final answer:
To evaluate the given expression, perform calculations step-by-step, which yields the final result of -5350.8.
Step-by-step explanation:
To evaluate the expression a b cd^2 given the values a=78, b=-7/16, c=0.8, and d=14, we follow these steps:
- First, square the value of d: 142 = 196.
- Then, multiply the squared value by c: 196 x 0.8 = 156.8.
- After that, multiply the result by b: 156.8 x (-7/16) = -68.6.
- Finally, multiply this result by a: -68.6 x 78 = -5350.8.
Therefore, the evaluated expression is -5350.8.
