Question

(-7/5)power-3×(6/-7)power-2​

Answer 1

Answer:

According to me this will be the right solution and answer

Answer 2

$\large\underline\bold{ANSWER \huge{\checkmark}}$

$\dashrightarrow \bigg( \dfrac{-7}{5}\bigg)^{-3}\times \bigg( \dfrac{6}{-7}\bigg)^{-2}$

$\dashrightarrow \bigg( \dfrac{-5}{7}\bigg)^3 \times \bigg( \dfrac{ -7}{6}\bigg)^2\:---\boxed{a^{-m}= \dfrac{1^m}{a^m}}$

$\dashrightarrow \dfrac{-125}{343} \times \dfrac{49}{36}$

$\dashrightarrow \dfrac{-125}{\cancel{343}} \times \dfrac{\cancel{49}}{36}$

$\dashrightarrow \dfrac{-125}{7\times 36}$

$\dashrightarrow \dfrac{-125}{252}$

$\large{\boxed{\bf{ \star\:\: \dfrac{-125}{252}\:\: \star}}}$
