Hello, I need help finding the solutions of the equation log base 2 (x+8)+2=2 log base 2 (x)

yuradex [85]

$\bf log_{{ a}}\left( \frac{x}{y}\right)\implies log_{{ a}}(x)-log_{{ a}}(y)
\\\\\\
% Logarithm of exponentials
log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)
\\\\\\
{{ a}}^{log_{{ a}}x}=x\impliedby \textit{log cancellation rule}\\\\
-----------------------------\\\\$

$\bf log_2(x+8)+2=2log_2(x)\implies log_2(x+8)-2log_2(x)=-2
\\\\\\
log_2\left(\cfrac{x+8}{x^2} \right)=-2\implies 2^{log_2\left(\cfrac{}{}\frac{x+8}{x^2} \right)}=2^{-2}\implies \cfrac{x+8}{x^2}=\cfrac{1}{2^2}
\\\\\\
4x+32=x^2\implies 0=x^2-4x-32
\\\\\\
0=(x+4)(x-8)\implies 
\begin{cases}
0=x+4\implies &-4=x\\
0=x-8\implies &8=x
\end{cases}$

anastassius [24]

Answer:

By figuring out the benchmark, you can determine which fractions are larger or smaller than each other. ... In order to be exact when comparing and ordering fractions, you have to find a common denominator for all of the fractions. Then, compare or order the fractions by looking at the value of the numerator.

Solve for x<br> 1(x-2) = -5.5

Dafna1 [17]

Answer:

x = -3.5

Step-by-step explanation:

Divide both sides by 1 to get rid of the 1

x - 2 = -5.5

Add 2 on both sides

x = -3.5
