Question
use laws of exponents to simplify:
${(81)}^{n}. {3}^{5} - {(3)}^{4n - 1}(243) \\ \div \\ ({9}^{2n} ) ({3}^{3} )$
plz solve this



these are seven laws you can use to solve the question written above:

1).
${a}^{m} . {a}^{n} = {a}^{m + n}$
2)
$( {a}^{m} ) {}^{n} = {a}^{mn}$
3)
$( {ab)}^{n } = {a}^{n} {b}^{n}$
4)
$( \frac{a}{b} ) {}^{n} = \frac{a {}^{n} }{b {}^{n} } \: \: b \: is \: not \: = to \: 0$
5)
$\frac{a {}^{m} }{a {}^{n} } = {a}^{m - n} \: \: \: \: a \: is \: not \: = to \: 0$
6)
${a}^{0} = 1 \: \: \: \:where \: a \: is \: not \: = to \: 0$
7)
${a}^{ - n} = \frac{1}{ {a}^{n} } \: \: \: \: where \: a \: is \: not \: = to \: 0$
