2. Sederhanakan bilangan berpangkat berikut! 3 a.(2/3)⁴
b. (2/3)-⁵
![]()
b. (2/3)-⁵
Penjelasan dengan langkah-langkah:
A.
[tex] = {( \frac{2}{3} )}^{4} [/tex]
[tex] = \frac{ {2}^{4} }{ {3}^{4} } [/tex]
[tex] = \frac{2 \times 2 \times 2 \times 2}{3 \times 3 \times 3 \times 3} [/tex]
[tex] = \frac{16}{81} [/tex]
[tex] \: [/tex]
B.
[tex] = {( \frac{2}{3} )}^{ - 5} [/tex]
[tex] = {( \frac{3}{2} )}^{5} [/tex]
[tex] = \frac{ {3}^{5} }{ {2}^{5} } [/tex]
[tex] = \frac{3 \times 3 \times 3 \times 3 \times 3}{2 \times 2 \times 2 \times 2 \times 2} [/tex]
[tex] = \frac{243}{32} [/tex]
