From the picutre, we can assume it wants the number in scientific notation, so, we need the coefficient as a number between 0 and 10 (not includint 10) and the appropriate exponent.
The prefix "T" means Tera, and it is equivalent of 10¹². So, at first, we have:
[tex]12Tm=12\times10^{12}m[/tex]
However, the coefficient is greater than 10, so we have to fix it by doing:
[tex]12Tm=12\times10^{12}m=12\times10\times10^{12}m=12\times10^{13}m[/tex]
So, the number, in scietific notation is:
[tex]12\times10^{13}m[/tex]
