Answer 1

Let the quotient be x

so,

(-5/7)^-2/x= (-10/21)^-3

(-7/5)^2/x= (-21/10)^3

49/25*1000/9261=x (in this step we just open the brackets and take x on one side)

x=(-40/189)

Hope this helps!

Let me know if I was correct or not

Answer 2

Answer:

[-(7)^2×40]/(21)^3 = -1960/9261

Step-by-step explanation:

(-5/7)^-2 can be written as (-7/5)^2= 49/25

and, (-10/21)^-3 can be written as (-21/10)^3= -9261/1000.

Let the no. to be be divided be x

So,

49/25÷x=-9261/1000

49/25×1000=9261x

49×40= -9261x

-1960/9261= x

x= -[(7)^2×40]/(21)^3 or -1960/9261 (simplified)..
