Answer:
Option D is correct
[tex]d^{8}[/tex]
Step-by-step explanation:
Given the expression: [tex]d^3 \cdot d^5[/tex]
Use exponents rule:
[tex]x^a \cdot x^b = x^{a+b}[/tex]
Apply the rule in the given expression;
[tex]d^3 \cdot d^5[/tex]
[tex]d^{3+5}[/tex]
[tex]d^{8}[/tex]
Therefore, the correct simplification of the given expression is, [tex]d^{8}[/tex]
