Answer:

[tex]x = \frac{3in(2)}{in(6)} - 2[/tex]

Solving steps:

[tex]-›6 {}^{x + 2} = 8[/tex]

Apply exponents rule

[tex]-›(x +2)in(6) = in(8)[/tex]

Solve for (x + 2) in(6) = in(8)

[tex]-›x = \frac{3in(2)}{in(6)} - 2[/tex]

[tex]\\ \rm\rightarrowtail 6^{x+2}=8[/tex]

[tex]\\ \rm\rightarrowtail (6)^{x+2}=2^3[/tex]

[tex]\\ \rm\rightarrowtail ln6^{x+2}=ln2^3[/tex]

[tex]\\ \rm\rightarrowtail (x+2)ln6=3ln2[/tex]

[tex]\\ \rm\rightarrowtail xln6+2ln6=3ln2[/tex]

[tex]\\ \rm\rightarrowtail xln6+2ln2+2ln3=3ln2[/tex]

[tex]\\ \rm\rightarrowtail xln6+2ln3=3ln2-2ln2[/tex]

[tex]\\ \rm\rightarrowtail xln6+2ln3=ln2[/tex]

[tex]\\ \rm\rightarrowtail xln3+xln2+2ln3=ln2[/tex]

[tex]\\ \rm\rightarrowtail (x+2)=\dfrac{ln8}{ln6}[/tex]

[tex]\\ \rm\rightarrowtail x=\dfrac{ln8}{ln6}-2[/tex]

Another

[tex]\\ \rm\rightarrowtail (x+2)ln6=ln8[/tex]

[tex]\\ \rm\rightarrowtail (x+2)ln6=ln2^3[/tex]

[tex]\\ \rm\rightarrowtail (x+2)ln6=3ln2[/tex]

[tex]\\ \rm\rightarrowtail x+2=\dfrac{3ln2}{ln6}[/tex]

[tex]\\ \rm\rightarrowtail x=\dfrac{3ln2}{ln6}-2[/tex]
