Question

Log2(0.5)= ??? помогите, пожалуйста

Answer 1

log2(2^-1)=-1 .......

Answer 2

Этот предмет можно представить по-другому, как

$log_{2} (\frac{1}{2} )$, тогда, т.к. $\frac{1}{2}$  это $2^{-1}$ степени, логарифм будет равен -1

Ответ: -1

Answer 3

To calculate the value of log base 2 of 0.5, we need to find out what exponent we need to raise 2 to in order to get 0.5. In mathematical terms:

log2(0.5) = x

This can be rewritten as:

2^x = 0.5

To find the value of x, we can use the fact that 0.5 is the same as 1/2:

2^x = 1/2

Now, to find the value of x, we can take the logarithm of both sides with base 2:

x = log2(1/2)

The value of log2(1/2) is -1.

So, log2(0.5) = -1.
