Answer:
1.3 times 10 to the 25th power
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
5.6 is the correct answer because 1.3 +4.3 would be 5.6 so the next one in the sequence is 9.9
Find how many mm are in 25m (by multiplying 25 by 1000) and convert that answer to km.
