Step-by-step explanation:
step 1: multiply [tex]2^m[/tex] by [tex]3^n[/tex]
2 × 3 = 6
to times power you must add them
eg: [tex]x^3[/tex] × [tex]x^4[/tex]
3+4=7
=[tex]x^7[/tex]
[tex]2^m[/tex] × [tex]3^n[/tex] = [tex]6^{m+n}[/tex]
step 2: rearrange
[tex]6^{m+n}[/tex] = 108
can you do this step by yourself
