Question

log x square - 5 base 2 =2 x=? ​

Answer 1

Answer:

we know that

$log_{a}(b) = y$

then

$b = a {}^{y}$

solution

$log_{2}(x {}^{2} - 5) = 2$

therefore,

$x {}^{2} - 5 = 4$

$x {}^{2} = 9$

$x = + - (3)$

so X = 3 or -3

Answer 2

formula:

$log_{a}(b) = y$

then :

$b = a {}^{y}$

solution

$log_{2}(x {}^{2} - 5) = 2$

thus ,

$x {}^{2} - 5 = 2 {}^{2}$

$x {}^{2} - 5 = 4$

$x {}^{2} = 9$

$x = (3)$

so X = 3 or -3
