Question
Earth has a new surface of 1.97x10^8 square miles. A new planet has a surface area 13 times the surface area of Earth.
What is the surface area of the new planet?
Do I multiply 1.97x13 or do I multiply 13x10^8? that's what i'm confused about.

Online "*" is used to indicate multiplication, since "x" can be confused with representing an unknown.
1.97*13 = 25.61
2.561*10^9
1.97*13 = 25.61
2.561*10^9
