Final answer:
The 8th harmonic number can be represented by the expression: H8 = 1 + 1/2 + 1/3 + ... + 1/8
Step-by-step explanation:
The harmonic number is a mathematical concept denoted by H_n, where n is a positive integer. The harmonic number is defined as the sum of the reciprocals of the first n natural numbers.
The 8th harmonic number can be represented by the expression:
H8 = 1 + 1/2 + 1/3 + ... + 1/n
Plugging in the value of 8, we get:
H8 = 1 + 1/2 + 1/3 + ... + 1/8
Calculating the value of this sum gives us the value of the 8th harmonic number.
