Properties of Logarithms

Question 2 • LCSD-CR-Mathematics for College Algebra-S2-1200710

Which of the following did you include in your solution?

Answer

Use the quotient property to rewrite the expression.

Write the difference of logs as the quotient log((d+1)/d).

Substitute 1 for d to get log(2).

Since log(2) = 0.30, the probability that the number 1 is the leading digit is about 30%.
