Question

If 3^n ×9 × 3^2n - (9×3)^n = 1/27
Then find the value of n^2


Step by step solution plz.....​

Answer 1

Answer:

n²=16 only if question is

(9n × 3² × 3n – (27)^n)/ (3³)^5 × 2³ = (1/27)

Explanation:

we can go like this

3^n x 3² x3^2n-3^3n =1/27

3^3n(3²-1) = 3^-3

3^3n x 8 =3^-3

here 8 makes confusion

Question is wrong

Question is maybe

(9n × 3² × 3n – (27)^n)/ (3³)^5 × 2³ = (1/27)
