Question

Which of the following is not equal to `((-5)/4)^4`?

विकल्प

• `(-5)^4/4^4`

• `5^4/(-4)^4`

• `- 5^4/4^4`

• `(-5/4) xx (-5/4) xx (-5/4) xx (-5/4)`

Answer 1

`bb(- 5^4/4^4)`

Explanation:

We know that, `(p/q)^m = p^m/q^m`

So, `((-5)/4)^4 = (-5)^4/(4)^4` or `((-5)/4)^4 = (5)^4/(-4)^4`

or `((-5)/4)^4 = ((-5)/4) xx ((-5)/4) xx ((-5)/4) xx ((-5)/4)`

Hence, `- 5^4/4^4` is not equal to 1.
