Answer 2

ur answer is option (II)

•°• cube of a negative number is always negative .

here is the proof :)

when we cubes any number, we just simply multiply the number by itself 3 times.

i.e. , cube of 3 = 3×3×3

= 27

this was a case of positive no.

let's take a negative one ,ok

cube of -5 = (-9)×(-9)×(-9)

= 81×(-9)

= -729 ✔✔✔

so, it has been proved that cube of a negative integer/no. will always a negative no.

So, I think that u r clear now ...
