Here are the approximate populations of three countries, expressed in scientific notation: Panama: 4 × 10 6 ; Peru: 3.2 × 10 7 ;
grigory [225]

Using scientific notation, the power of 10 that should be put on the label is of 10^7, hence x = 7.

<h3>What is scientific notation?</h3>

A number in scientific notation is given by:

a \times 10^b

With the base being a \in [1, 10).

In this problem, we don't want to increase the base values much. Panama's population can be represented as:

4 \times 10^6 = 0.4 \times 10^7

Hence, the power of 10 that should be put on the label is of 10^7, hence x = 7.
