Answer 1

Answer:

-3/7^7

Step-by-step explanation:

(-3/7)^3*-(3/7)^4

=(-3/7)^3+4

=3/7^7

Answer 2

ANSWER✔

$\sf\therefore \bigg( \dfrac{-3}{7} \bigg)^3 \times \bigg( \dfrac{-3}{7} \bigg)^4$

$\sf\implies \bigg( \dfrac{-27}{343} \bigg) \times \bigg( \dfrac{-81}{2401} \bigg)$

$\sf\implies \dfrac{ 2187}{823543}$

$\large{\boxed{\bf{ \star\:\: \dfrac{ 2187}{823543} \:\: \star}}}$
