The image shows an arithmetic expression involving several terms with various operations. I'll first break it down:

The numerator appears to be: $35^{11} \cdot 49^{1} \cdot (-12) - 31$

The denominator is: $10^{12} \cdot 6^{30} \cdot (-14)$

This is a division of the numerator by the denominator.

Would you like me to calculate this entire expression or simplify it step by step? Let me know if there are any specific details you'd like to focus on!
