Question

The world's largest ocean,the Pacific Ocean,has an area of about 200000000 km²,which can be written as 2 x 10ⁿ km².What is n?

Answer 1

The exponent n that makes 2 x 10ⁿ km² equivalent to the area of the Pacific Ocean, 200,000,000 km², is 8.

Step-by-step explanation:

To express the area of the Pacific Ocean, which is 200,000,000 km², in the form of 2 x 10ⁿ km², we need to determine the exponent n that makes the expression equivalent to 200,000,000 km². The scientific notation for 200,000,000 is 2 x 10⁸. Therefore, the exponent n in the given expression 2 x 10ⁿ km² must be equal to 8.
