(-3/5)power 4 - (-9)power 2/54
with full explanation

Dear Student,

{(\frac{3}{5})}^{4} - \frac{{(- 9)}^{2}}{54} = \frac{3 \times 3 \times 3 \times 3}{5 \times 5 \times 5 \times 5} - \frac{81}{54} = \frac{81}{625} - \frac{81}{54} = 81 [\frac{1}{625} - \frac{1}{54}] = 81 [\frac{54 - 625}{625}] = 81 [\frac{- 571}{625}] = \frac{- 571 \times 81}{625} = \frac{- 46251}{625}
