The simplified form of the expression will be [tex]27m^6n^{12[/tex]
Given the indices expression
[tex](3m^2n^4)^3[/tex]
Using the law of indices expressed as:
[tex](a^m)^n=a^{mn}[/tex]
This expression will become:
[tex](3m^2n^4)^3\\= 3^3(m^2)^3(n^4)^3\\= 27m^6n^{12[/tex]
Hence the simplified form of the expression will be [tex]27m^6n^{12[/tex]
