Answer 1

9.99 *10 ^ 6 km

Explanation:

Given that the surface area of Canada is 9,984,671 square kilometers.

The standard form of scientific notation is expressed as;

A * 10^n

A is any values between 1 to 9

n is an integer

Given

9,984,671 square kilometers.

9,984,671 = 9.99 *10 ^ 6

Hence the required scientific notation is 9.99 *10 ^ 6
