Solve.

Q 1.) [tex]3^{3x}+3^{3x+2}=30[/tex]

Q 2.) [tex]3^{2x}-12(3^{x})+27=0[/tex]

2. Relevant equations

[tex](a^{n}){b}=a^{nb}[/tex]

[tex]a^{n}(a^{b})=a^{n+b}[/tex]

3. The attempt at a solution

Q 1.) [tex]3^{3x}+3^{3x+2}=3^{1}+3^{3}[/tex]

Q 2.) [tex]3^{2x}+3^{3}=12(3^{x})[/tex]

[tex]3^{2x}+3^{3}=(3^{1}+3^{2})(3^{x})[/tex]
