EXPLANATION:
Given;
We are given the following exponential expression;
[tex]4^3\times4^5[/tex]
Required;
We are required to simplify the expression
Step-by-step solution;
We shall begin by applying the rule of exponents, which is;
[tex]a^b\times a^c=a^{b+c}[/tex]
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;
[tex]\begin{gathered} 4^3\times4^5=4^{3+5} \\ 4^3\times4^5=4^8 \end{gathered}[/tex]
Therefore,
ANSWER:
Option D is the correct answer.
[tex]4^8[/tex]
