Answer 1

Answer:

The smallest number by which 1944 should be multiplied so that it becomes a perfect cube is option ( i):3

1944×3=5832

3√5832=18

So,

18 is the answer. As 18 is perfect square of 9.

Answer 2

Answer:

The smallest no. is 3 by which 1944 should be multiplied so that it becomes a cube.

Step-by-step explanation:

We know that,

1944 = 2 * 2 * 2 * 3 * 3* 3 * 3* 3

= 2³ * 3³ * 3²

Clearly, we have seen that 3 should be multiplied to 1994 so that it will become a perfect cube.

i. e. 1994 * 3 = 5832 = (18)³
