Question

9 . 27^n = 3^5

Answer 1

\(9.27^n=3^5\)

\(\Rightarrow3^2.\left(3^3\right)^n=3^5\)

\(\Rightarrow3^2.3^3.3^n=3^5\)

\(\Rightarrow3^5.3^n=3^5\)

\(\Rightarrow3^n=3^5:3^5=1\)

\(\Rightarrow3^n=3^0\)

\(\Rightarrow n=0\)

Answer 2

9 . 27ⁿ = 3⁵

=> 9 . 27ⁿ = 243

=> 27ⁿ = 243 : 9 =

=> 27ⁿ = 27

=> 27¹ = 27

=> n = 1

Answer 3

9 . 27^n = 3^5

9. 27^n =  243

27^n     = 243 : 9

27^n     = 27

27^n     = 27^1

=> n = 1

Answer 4

9. 27^n = 3^5

27^n = 3^5 : 9

27^n = 243 : 9

27^n = 27

27^n = 27^1

=> n = 1
