Question

if x/y=(-1/3)^-3 ÷(2/3)^-4 find the valu of (x/y)^-3​

Answer 1

Answer:

If x/y = 2/3, then (x + y)/(x - y) = ?

A. 5

B. 1/5

C. -1/6

D. -1/5

E. -5

Any x and y satisfying x/y = 2/3 should give the same value for (x + y)/(x - y).

Say x=2 and y=3, then (x + y)/(x - y) = (2 + 3)/(2-3) = -5.
