Question

Condense the expression to a single logarithm. 3 log subscript 5 10 - 12 log subscript 5 7

Answer 1

A is correct

Explanation:

Mathematically from logarithmic laws, we have it that;

x log a = log a^x

and also;

log a - log b = log (a/b)

So we have;

log 5 10^3 - log 5 7^12

and finally log 5 (10^3/7^12)
