Question

9n/9-2=9^11 , what will be the value of n??​

Answer 1

Answer:

$n = 9 {}^{8}$

Explanation:

$sol {}^{n}$

$\frac{9n}{9 {}^{ - 2} } = 9 {}^{11}$

$= > 9n = 9 {}^{11} \times 9 {}^{ - 2}$

$= > 9n = 9 {}^{11 + ( - 2)}$

$= > 9n = 9 {}^{9}$

$= > n = \frac{9 {}^{9} }{9}$

$= > n = 9 {}^{9 - 1}$

$so \: \: \: n = 9 {}^{8}$
