Solution steps

(- \frac{2}{7})^{3}

Apply exponent rule:

(- a)^{n} = - a^{n},

if

n

is odd

(- \frac{2}{7})^{3} = - (\frac{2}{7})^{3}

= - (\frac{2}{7})^{3}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

(\frac{2}{7})^{3} = \frac{2 ^{3}}{7 ^{3}}

= - \frac{2 ^{3}}{7 ^{3}}

2^{3} = 8

= - \frac{8}{7 ^{3}}

7^{3} = 343

= - \frac{8}{343}
