Answer:
Correct Answer: D
Solution:
- $ 8^{2}\times 7^{2}\div \sqrt{196}-143={3^{?}} $
$ \Rightarrow $ $ 8^{2}\times 7^{2}\div 14-143={3^{?}} $
$ \Rightarrow $ $ 64\times \frac{49}{14}-143={3^{?}} $
$ \Rightarrow $ $ 244-143={3^{?}} $
$ \Rightarrow $ $ {3^{?}}=81 $
$ \Rightarrow $ $ {3^{?}}=3^{4} $
$ \Rightarrow $ $ ?=4 $
