Jawaban:
a.
[tex] {5}^{4} \times {5}^{ - 6} \\ = {5}^{4 + ( - 6)} \\ = {5}^{4 - 6} \\ = {5 }^{ - 2} \\ = \frac{1}{ {5}^{2} } \\ = \frac{1}{25} [/tex]
b.
[tex]( - { \frac{1}{4} })^{ - 1} \times ( - { \frac{1}{4} })^{0 } \times ( - { \frac{1}{4} })^{4} \\ = ( - { \frac{1}{4} })^{ - 1 + 0 + 4} \\ = ( - { \frac{1}{4} })^{3} \\ = ( - \frac{ {1}^{3} }{ {4}^{3} } ) \\ = - \frac{1}{64} [/tex]
c.
[tex] {5}^{8} \times {5}^{4} \div {5}^{3} \\ = {5}^{8 + 4 - 3} \\ = {5}^{9} \\ = 1.953.125[/tex]
f.
[tex] ({ {2}^{ 3} })^{4} \div ( { \frac{1}{2} })^{2} \\ = {2}^{3 \times 4} \div ({2}^{ - 1})^{2} \\ = {2}^{12} \div {2}^{ - 2} \\ = {2}^{12 - ( - 2)} \\ = {2}^{12 + 2} \\ = {2}^{14} \\ = 16.384[/tex]
