Question

Answer 1

\(\Leftrightarrow3^{3n}\cdot3^{2n}=3^{54}:3^4\\ \Leftrightarrow3^{5n}=3^{50}\\ \Leftrightarrow5n=50\Leftrightarrow n=10\)

Answer 2

\(\Leftrightarrow3^{3n}.3^{2n}=3^{54}:3^4\\ \Leftrightarrow3^{5n}=3^{50}\\ \Leftrightarrow5n=50\\ \Leftrightarrow n=10\)

Answer 3

3^3n . 3^2n = 3^54 : 3^4

3^5n = 3^50

5n = 50 

n = 10
