(m − n)2 − (m − 3n)2

The question seems to be a bit unclear, but I'll try to interpret it as best as I can. Step 1: Solve the operation inside the parentheses first, which is (137 - 58). The result is 79. Step 2: Multiply the result by 2334. The result is 184386. Step 3: Divide 157 by 47. The result is approximately 3.34 (rounded to two decimal places). Step 4: Multiply the result from step 3 by 2 raised to the power of 13. The result is approximately 27341.12 (rounded to two decimal places). Step 5: Add the results from step 2 and step 4. The result is 211727.12. Step 6: Multiply the result by -2. The final result is -423454.24. ####
