    0.7525

Answer

Correct Answer: 0.6990

Explanation

Introduction / Context:Use the identity 10 = 2 * 5 and the logarithm of a product to relate log(2) and log(5).

Given Data / Assumptions:log_10(2) = 0.3010 and log_10(10) = 1.

Concept / Approach:Since log(10) = log(2) + log(5), we have log(5) = 1 − log(2).

Step-by-Step Solution:

log_10(5) = 1 − 0.3010 = 0.6990

Final Answer:0.6990
