Here are the approximate populations of three countries, expressed in scientific notation: Panama: 4 × 10 6 ; Peru: 3.2 × 10 7 ; Thailand: 7 × 10 7.

Decide what power of 10 to put on the label for the rightmost tick mark of this number line so that all three countries’ populations can be distinguished.

Sagot :

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

What is scientific notation?

A number in scientific notation is given by:

[tex]a \times 10^b[/tex]

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

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

[tex]4 \times 10^6 = 0.4 \times 10^7[/tex]

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