A National Park covers an area of 1.24x10^6 acres. A nearby national forest covers an area of 2.1x10^6 acres. What is the total number of acres in the park and the forest together? Write the answer in scientific notation.

To find the total number of acres in the park and the forest together, we need to add their areas.

The area of the national park is 1.24x10^6 acres.

The area of the national forest is 2.1x10^6 acres.

To add these areas, we line up the numbers and add:
1.24x10^6
+2.1x10^6
-----------
3.34x10^6

Therefore, the total number of acres in the park and the forest together is 3.34x10^6 acres.
