Question

If /frac{x}{y}=(/frac{-1}{3})^{-3}÷(/frac{2}{3})^{-4},find the value of: (/frac{x}{y})^{-3}​

Answer 1

Step-by-step explanation:

Explanation:

Step 1: You have to Multiply the

3

and the

2

together and then add the

1

and that would all be over

3

. Then you get

2

1

3

=

2

×

3

+

1

3

=

7

Step 2: You do the same thing which is

2

times

1

and then add

1

and that would be all over

2

. Then you get

1

1

2

=

1

2

+

1

2

=

Step 3: Combine together as

3

−

2

Next, you have to have a common denominator of

6

.

7

3

times

2

both top and bottom. Then

3

2

is going to be times

3

both top and bottom.
