– 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 Split into two  From laws of indices Applying the above law, we have   Hence, Kristoph’s expression in scientific notation is
