NOMOR 3.

a. ${5}^{ - 2} = frac{1}{ {5}^{2} } = frac{1}{25}$

b. ${( frac{2}{3}) }^{ - 3} = frac{1}{ ({ frac{2}{3} )}^{3} } = frac{1}{( frac{8}{27} )} = frac{27}{8}$

NOMOR 4.

a. $5( {x}^{2} - y)( { {x}^{2} - {y}^{2} })^{0}$

$= 5 times ( {x}^{2} - y) times 1$ $= 5( {x}^{2} - y) = 5 {x}^{2} - 5y$

b. $frac{(3x + 2y)}{ ({3x + 2y})^{0} } = frac{(3x + 2y)}{1} = 3x + 2y$

NOMOR 5.

a. $frac{ {2}^{4} }{ {2}^{2} } = {2}^{4 - 2} = {2}^{2} = 4$

b. ${p}^{2} times {p}^{3} = {p}^{2 + 3} = {p}^{5}$

c. ${( frac{1}{2} )}^{3} = frac{ {(1)}^{3} }{ {(2)}^{3} } = frac{1 times 1 times 1}{2 times 2 times 2} = frac{1}{8}$

d. ${( frac{ - 2}{3}) }^{2} = frac{ {( - 2)}^{2} }{ {(3)}^{2} } = frac{( - 2) times ( - 2)}{3 times 3} = frac{4}{9}$

e. ${( frac{ - 2}{3}) }^{ - 2} = frac{1}{ {( frac{ - 2}{3}) }^{2} } = frac{1}{ (frac{( - 2) times ( - 2)}{3 times 3} )} = frac{1}{( frac{4}{9} )} = frac{9}{4}$
