Question

Помогите пожалуйста!

Answer 1

$frac{5^n(5^2+5-1)}{5^n(5^2-1)} = frac{29}{24}$

$frac{27^n*27-3^n*27}{9*(3^{3n} -3^n)} = frac{27(27^n-3^n)}{9( 3^{3n} -3^n)} = frac{3( 3^{3n} -3^n)}{ 3^{3n} -3^n} =3$

Answer 2

(5^(n+2) + 5^(n+1)-5^n)/(5^(n+2) - 5^n)=5^n *(25+5-1)/5^n * (25-1)=29/24=1 5/24

(27^(n+1)- 3^(n+3))/9*3^n * (3^2n - 1)=(3^(3n+3) -3^(n+3))/3^(n+2) *(3^2n - 1)=
=3^(n+3)*(3^2n - 1)/3^(n+2) *(3^2n - 1)=3
