(1/5)³; (4/3)²; (2/3)⁴; (10/3)³. Помогите решить!!

Решите задачу:

$( \frac{1}{5} ) ^{3} = \frac{1}{5} * \frac{1}{5}* \frac{1}{5}= \frac{1}{125} \\ (\frac{4}{3} ) ^{2} =\frac{4}{3}*\frac{4}{3}= \frac{16}{9} \\ ( \frac{2}{3} ) ^{4} =\frac{2}{3} *\frac{2}{3} *\frac{2}{3} *\frac{2}{3} = \frac{16}{81} \\ ( \frac{10}{3} ) ^{3} =\frac{10}{3} *\frac{10}{3} *\frac{10}{3} = \frac{1000}{27}$
