Answer :
We are given that [tex]$1$[/tex] megaton equals [tex]$10^6$[/tex] tons. To convert [tex]$57$[/tex] megatons to tons, we multiply by the conversion factor:
[tex]$$
\text{tons} = 57 \times 10^6.
$$[/tex]
Performing the multiplication, we obtain:
[tex]$$
\text{tons} = 57\,000\,000.
$$[/tex]
Thus, [tex]$57$[/tex] megatons is equal to [tex]$57\,000\,000$[/tex] tons.
[tex]$$
\text{tons} = 57 \times 10^6.
$$[/tex]
Performing the multiplication, we obtain:
[tex]$$
\text{tons} = 57\,000\,000.
$$[/tex]
Thus, [tex]$57$[/tex] megatons is equal to [tex]$57\,000\,000$[/tex] tons.
