this is a correct answer please solve it fast ​

Answer 1

Answer:

-1/(28) ^ 3  [ You have put the negative sign for 28, but usually it's put before the numerator. Don't worry, it's the same ]

Step-by-step explanation:

( -4 × 7 )^-3

( -28 )^-3

( -1/28)^3

[ When the power is negative ( here, -3), to make it positive, we take the reciprocal of the number- Eg: If it is (a/b)^-2, then the answer will be (b/a)^2. So you apply the same thing here. ]

Here, the reciprocal will be ( -1/28 ).

P.S.- Always remember that if the negative sign (-) should always be there before the numerator and not the denominator. It's one and the same.
