Find the cube roots of each of the following integers: `-125` (ii) `-5832` (iii) `-2744000` `-753571` (iv) `32768`

Text Solution

Verified by Experts

By using prime factorization method, we can find:
(i) `-125`
`-125=-1xx5xx5xx5`
`-root(3)(125)=-5`

(ii) `-5832`
`-5832=-1xx18xx18xx18`
`-root(3)(5832)=-18`

(iii) `-2744000`
`-2744000=-1xx140xx140xx140`
`-root(3)(2744000)=-140`

(iv) `-753571`
`-753571=-1xx91xx91xx91`
`-root(3)(753571)=-91`

(v) `32768`
`32768=32xx32xx32`
`root(3)(32768)=32`
