Final answer:
The expression log(15/7) can be simplified to log(15) - log(7) using the property of logarithms that states the logarithm of a quotient is the difference of the logarithms of the numerator and the denominator.
Step-by-step explanation:
The expression equivalent to log (15/7) can be found using the property of logarithms that the logarithm of the number resulting from the division of two numbers is the difference between the logarithms of the two numbers. In this case, log (15/7) can be written as log 15 - log 7.
To find the value of log 15 and log 7, we can use a calculator or table of logarithms. For example, log 15 ≈ 1.176 and log 7 ≈ 0.845. Therefore, log (15/7) ≈ 1.176 - 0.845 ≈ 0.331.
