Question

1) log 18 36 + log 18 0,5​

Answer 1

Ответ: 1

Пошаговое объяснение:

Используем св-во логарифмов:

$log_{a}b+log_{a}c=log_{a}(b*c)$

$log_{18}36+log_{18}0,5=log_{18}(36*0,5)=log_{18}(18)= 1$

Answer 2

1 логорифм равен 1.24
2 логорифм равен -0.24
1.24+(-0.24)=1

Answer 3

To simplify the expression $\log_{18}36 + \log_{18}0.5$, you can use the properties of logarithms.

1. Use the fact that $\log_a(b) + \log_a(c) = \log_a(b \cdot c)$:

$\log_{18}36 + \log_{18}0.5 = \log_{18}(36 \cdot 0.5)$

2. Calculate the product inside the logarithm:

$\log_{18}(18)$

3. Since $\log_a(a) = 1$ for any positive $a$, the expression simplifies further:

$1$

So, $\log_{18}36 + \log_{18}0.5 = 1$.
