Question

What should be multiplied to the
following numbers to make them a
perfect cube?
a) 2,200 b) 1,340
c) 3,378​

Answer 1

a) therefore,if we subtracted 5×11×11 from 2200 we will get it's perfect cube...

b) 1340 = 2 * 2 * 5 * 67. Hence, 224450 should be multiplied to 1340 to make it a perfect cube.

c) To make it a perfect cube we multiply it by 5. Thus, 68600 × 5 = 2 × 2 × 2 × 5 × 5 × 5 × 7 × 7 × 7 = 343000, which is a perfect cube.
