(⅕)²×(⅕)-⁴×(⅕)-⁴

Jawab:

15625

Penjelasan dengan langkah-langkah:

Pahami sifat perpangkatan berikut

a^m times a^n = a^{m + n}\a^{-n} = frac{1}{a^n}

Maka,

(frac{1}{5})^2 times (frac{1}{5})^{-4} times (frac{1}{5})^{-4}\= (frac{1}{5})^{2 + (-4) + (-4)}\= (frac{1}{5})^{-6}\= frac{1}{(frac{1}{5})^6}\= frac{1}{(frac{1^6}{5^6})}\= frac{1}{(frac{1}{15625})}\= 15625
