Answer 1

Step-by-step explanation:

Given;

We are given the following exponential expression;

`4^3*4^5`

Required;

We are required to simplify the expression

Step-by-step solution;

We shall begin by applying the rule of exponents, which is;

`a^b* a^c=a^(b+c)`

Note that this rule applies when the base is the same for both sides of the expression.

The base here is 4 on both sides, hence we'll have;

`\begin{gathered} 4^3*4^5=4^(3+5) \\ 4^3*4^5=4^8 \end{gathered}`

Therefore,

ANSWER:

Option D is the correct answer.

`4^8`
