Answer:

#6.2955*10^2#

Explanation:

Make sure you move your decimal to where your number will be between 1 and 10. Then if you moved your decimal to the left, your exponent for 10 will increase for each place you moved it; if you moved your decimal to the right, your exponent for 10 will decrease for each place you moved it.

#629.55# must have it's decimal moved twice to the left in order for it to be in between 1 and 10.

#6.2955*10^2# will be your answer. And if you want to round, you could just round it to #6.3*10^2#.
