Question

evaluate the following: (-5 upon 6 )^-3​

Answer 1

$\bf \Bigg ( - \dfrac{5}{6} \Bigg )^{-3}$

$\sf \implies \Bigg ( - \dfrac{6}{5} \Bigg )^{3} \qquad \qquad \qquad .... \Bigg [as \ {a}^{-1} = \dfrac{1}{a} \Bigg ]$

$\sf \implies - \dfrac{6}{5} \times - \dfrac{6}{5} \times - \dfrac{6}{5}$

$\bf \implies - \dfrac{216}{125}$

Hope it helps.
