Answer:
- Shannon's expression in scientific notation is 
- Kristoph's expression in scientific notation is 
Step-by-step explanation:
Given
Shannon’s expression: 
Kristoph’s expression: 
Required
What is the value of their expressions written in standard form
First, we solve Shannon's expression:

Writing the expression properly

Split into two


From laws of indices 
Applying the above law, we have


Hence, Shannon's expression in scientific notation is 
Applying the same steps on Kristoph's expression; we have

Writing the expression properly
