– 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
