Question

$log_{2}x + log_{2}(x + 2) = 3$
​

Answer 1

Respuesta:

Input

log(2, x) + log(2, x + 2) = 3

Result

log(x)/log(2) + log(x + 2)/log(2) = 3

Alternate form assuming x is real

log(x) + log(x + 2) = log(8)

Alternate forms

log(x) + log(x + 2) = 3 log(2)

(log(x) + log(x + 2))/log(2) = 3

Alternate form assuming x is positive

log(x (x + 2)) = log(8)

Solution

x = 2
