검증된 단계별 안내1
Understand that a 10-fold dilution means the solution is diluted to 1/10th of its previous concentration each time.
Recognize that performing 4 consecutive 10-fold dilutions means multiplying the dilution factors together: each step contributes a factor of 10.
Express the total dilution factor as the product of the individual dilution factors: \(10 \times 10 \times 10 \times 10\).
Rewrite the product using exponents: \$10^4$.
Calculate the value of \$10^4$ to find the final dilution factor relative to the original solution.
