tentukan hasil perpangatan berikut!
a.
[tex]( \frac{2}{7} )^{ - 3} [/tex]
b.
[tex](( \frac{1}{5})^{2} )^{ - 2} [/tex]
![]()
a.
[tex]( \frac{2}{7} )^{ - 3} [/tex]
b.
[tex](( \frac{1}{5})^{2} )^{ - 2} [/tex]
Penjelasan dengan langkah-langkah:
[tex] = {( \frac{2}{7} )}^{ - 3} [/tex]
[tex] = {( \frac{7}{2} )}^{3} [/tex]
[tex] = \frac{ {7}^{3} }{ {2}^{3} } [/tex]
[tex] = \frac{343}{8} [/tex]
[tex] \: [/tex]
[tex] = {( {( \frac{1}{5} )}^{2} )}^{ - 2} [/tex]
[tex] = {( \frac{1}{5} )}^{2 \times ( - 2)} [/tex]
[tex] = {( \frac{1}{5} )}^{ - 4} [/tex]
[tex] = {( \frac{5}{1} )}^{4} [/tex]
[tex] = {5}^{4} = 625[/tex]
