It seems like you're asking for help related to comparing weights or masses, possibly involving scientific notation. If you're looking to convert numbers from scientific notation to standard form for comparison, please provide the specific numbers or expressions you would like to work with.
If the responses you listed (4 times heavier, 2 times heavier, 40 times heavier) are comparisons of weights based on some initial value, I can help clarify or analyze those as well. Just let me know!
