Choose the correct simplification of the expression f4 • f8.

Question

Choose the correct simplification of the expression

=

Step-by-step explanation:

Topic: Indices

There are two methods of doing this;

Method 1

----- Expand both indices

= -- The total number of f is 12, so we have

=

So,

This method is not advisable when dealing with a large indices; hence, the need for method 2.

Method 2

Applying law of indices;

The first law of indices

The first law of indices states: .

This means that when numbers in index form with the same base are multiplied by each other, the powers (indices) are added together.

Applying this law on

=

=

maybe i can

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
