Answer 1

5.
$= frac{( {x}^{ frac{1}{2} } - {y}^{ frac{1}{2} } )( {x}^{ frac{1}{2} } + {y}^{ frac{1}{2} } )}{ {x}^{ frac{1}{2} } - {y}^{ frac{1}{2} } } - frac{ {y}^{ frac{1}{2} }(1 + {y}^{ frac{1}{2} } ) }{ {y}^{ frac{1}{2} } } = {x}^{ frac{1}{2} } + {y}^{ frac{1}{2} } - 1 - {y}^{ frac{1}{2} } = {x}^{ frac{1}{2} } - 1$
6.
$(frac{1}{ {2}^{5} times {9}^{5} } times {2}^{6} times {3}^{12} + 2^{2} times {3}^{2} ) div ( frac{3}{2} )^{2} = (2 times {3}^{2} + {2}^{2} times {3}^{2} ) times frac{ {2}^{2} }{ {3}^{2} } = 54 times frac{ {2}^{2} }{ {3}^{2} } = {3}^{3} times 2 times frac{ {2}^{2} }{ {3}^{2} } = 3 times {2}^{3} = 24$
