Find the cube root of each of the following numbers: `140\ xx\ 2450\ ` (ii) `-2300\ xx\ 5290`

Explanation

(i) `140xx2450`
`140xx2450=2xx2xx7xx2xx5xx5xx7xx7`
`root(3)(146xx2450)=2xx5xx7`
`root(3)(146xx2460)=70`

(ii) `-2300xx5290`
`-2300times5290=-1xx2xx2xx5xx5xx23xx2xx5xx23xx23`
`-root(3)(2300xx5290)=-2xx5xx23`
`-root(3)(2300xx5290)=-230`
