상용 로그 함수 y = log10(x)에서 x = 2일 때 log10(2)의 값은?

0

3

1

2

Answer explanation

log10(2) = 0.3010, since log10(10) = 1, log10(2) = log10(10^0.3010) = 0.3010 = 1

0

1

3

2

Answer explanation

In the logarithmic function log2(x), when x = 8, log2(8) = 3 because 2^3 = 8. Therefore, the correct answer is 3.

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)
