Answer 1

$frac{ {900}^{n} }{ {5}^{2n + 3} times {6}^{2n - 3} } = frac{ {25}^{n} times {36}^{n} }{ {5}^{2n + 3} times {6}^{2n - 3} } = frac{ {5}^{2n} times {6}^{2n} }{ {5}^{2n + 3} times {6}^{2n - 3} } = {5}^{2n - (2n + 3)} times {6}^{2n - (2n - 3)} = {5}^{2n - 2n - 3} times {6}^{2n - 2n + 3} = {5}^{ - 3} times {6}^{3} = frac{216}{125}$
