Question

A lake covers a surface area of about 30.000 square miles. How can you show the stimated area of the lake as a whole number multiplied by a power of ten?

Answer 1

Area of the lake is 3 * 10^4 square miles

Explanation:

Here, we want to show the area of the lake as a whole number multiplied by a power of 10.

From the question, we are told that the area of the lake is 30,000 square miles.

So simply put, we want to express 30,000 as a whole number multiplied by a power of 10

Mathematically we can write 30,000 as 3 * 10,000

We can see that 10,000 is a power of 10 which can be written as 10^4 based on the number of zeros

Hence the area of the lake would be 3 * 10^4 square miles
