로그함수의 독립변수 간의 곱셈을 종속변수 간의 덧셈으로 변환하는 성질은?
logb(x) + logb(y) = logb(xy)
logb(x) - logb(y) = logb(x/y)
logb(x^2) = 2logb(x)
logb(LK) = logb(L) + logb(K)
Answer explanation
logb(x) + logb(y) = logb(xy) is the property that converts multiplication of independent variables in a logarithmic function to addition of dependent variables.

로그함수의 독립변수 간의 나눗셈을 종속변수 간의 뺄셈으로 변환하는 성질은?
logb(LK) = logb(L) + logb(K)
logb(x^2) = 2logb(x)
logb(x) - logb(y) = logb(x/y)
logb(x) + logb(y) = logb(xy)
Answer explanation
The property that converts division of independent variables in a logarithmic function to subtraction of dependent variables is logb(x) - logb(y) = logb(x/y)
