Question

3n× 9n+1/3n-1×27n-1=81​

Answer 1

Answer:

27n +1/3n -27n -1= 81

1/3n-1=81

1/3n=81+1

1/3n = 82

n= 82×3

n= 246

Answer 2

value of n is  246

Step-by-step explanation:

given term

3n × 9n + $\frac{1}{3}$ n - 1 × 27 n - 1 = 81

to find out

value of n

solution

in the given equation we have 1 unknown value value i.e  n

3n × 9n + $\frac{1}{3}$ n - 1 × 27 n - 1 = 81

27 n + $\frac{1}{3}$ n - 27 n = 81 + 1

here now we will cancel out +27 n with -27 n

so remaining term will be

$\frac{1}{3}$ n   = 82

so n will be

n = 82 × 3

n = 246

so value of n is  246
