I won't do your question but I will do a similar one and you can copy the technique.
1362.98
There needs to be just one non zero number in front of the decimal point: 1.36298
I have moved the decimal point 3 places, so the power will be 3
If it is a little number, less than 1, then the power will be negative
But, this is a big number, more than 9 so the power will be positive, that is, +3
so the answer is
1362.98 = 1.36298 x 10^3
i hope this helps and that you learn from it.
