Question

solve
its 81 on right side ​

Answer 1

Step-by-step explanation:

(3^2)^n×3^2=81

=>3^2n=81/9

=>3^2n=9

=>3^2n=3^2

=>2n=2

=>n=2/2

=>n=1

Answer 2

${ ({3}^{2}) }^{n} \times {3}^{2} = 81 \\ { {3}^{2n} } \times 9 = 81 \\ { {3}^{2n} } = \frac{81}{9} \\ {3}^{2n} = 9 \\ \\ 9 \: can \: be \: written \: as \: {3}^{2} \\ {3}^{2n} = {3}^{2} \\ 3 \: get \: cancels \\ 2n = 2 \\ n = \frac{2}{2} \\ n = 1$

$so \: option \: B) \: 1 \: is \: correct$
