Jawaban:

${8}^{2} times {4}^{ - 3} \ = 64 times frac{1}{ {4}^{3} } = 64 times frac{1}{64} = 1$

$( {2}^{3} )^{ frac{2}{3} } = {2}^{3 times frac{2}{3} } = {2}^{2} = 4$

3. (-5)⁶ / (-5)² =(-5)⁴

$frac{ {3}^{7} times {5}^{3} }{ {3}^{3} } = {3}^{7 - 3} times {5}^{3} = {3}^{4} times {5}^{3}$

$frac{(x {y}^{3})^{ - 1} }{( {x}^{ - 4} {y}^{2})^{ - 3} } \ = frac{ {x}^{ - 1} {y}^{ - 3} }{ {x}^{12} {y}^{ - 6} } \ = {x}^{( - 1 - 12)} {y}^{( - 3 - ( - 6))} \ = {x}^{ - 13} {y}^{3}$

$frac{( {4}^{2} )^{5} times ( frac{1}{2} )^{3} }{( frac{1}{2}) ^{2} times {4}^{2} } \ = frac{ {4}^{10} times frac{1}{8} }{ frac{1}{4} times 16} \ = frac{ {4}^{10} times frac{1}{8} }{4} \ = {4}^{10 - 1} times frac{1}{8} \ = {4}^{9} times frac{1}{8} \ = frac{262.144}{8} = 32.768$
