Answer:
255,300
Step-by-step explanation:
3.33×10^4=33,300. Then 2.22×10^5=222,000. Now add 33,300 plus 222,000 which is 255,300
Answer:
[tex]2.553 \cdot 10^5[/tex]
Step-by-step explanation:
(3.33 X 10^4 km) + (2.22 X 10^5 km)
First multiply the exponent with the given decimal number
[tex]3.33 \cdot 10^4= 3.33 \cdot 10000= 33300[/tex]
[tex]2.22 \cdot 10^5= 2.22 \cdot 100000= 222000[/tex]
Now we add both the numbers
[tex]33300 +222000= 255300[/tex]
Now write the answer into scientific notation
Move the decimal point after 2. we move 5 places to the left
So it becomes [tex]2.553 \cdot 10^5[/tex]
