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

To find the surface area of the new planet, you need to multiply the surface area of Earth by 13.

The surface area of Earth is given as 1.97x10^8 square miles.

To find the surface area of the new planet, multiply the surface area of Earth by 13:

(1.97x10^8) * 13

Multiplying the numbers:

1.97 * 13 = 25.61

To calculate the exponent:

10^8 * 10^0 = 10^(8+0) = 10^8

Therefore, the surface area of the new planet is 25.61x10^8 square miles.

To find the surface area of the new planet, you need to multiply the surface area of Earth by 13. However, the surface area of Earth is given in scientific notation as 1.97x10^8 square miles.

To multiply a number in scientific notation by another number, you multiply the coefficients (the numbers before the "x") and add the exponents (the numbers after the "x").

So, to find the surface area of the new planet, you would multiply:

(1.97) x (13) = 25.61

Then, you add the exponents:

10^8 x 10^0 = 10^8

So the surface area of the new planet is 25.61x10^8 square miles.
