Question

Find the smallet numbe by which

08 wt be mutiplied obtain a perfect cube​

Answer 1

Answer:

Prime factorising 2808, we get,

2808=2×2×2×3×3×3×13

=2³×3³×13¹

We know, a perfect cube has multiples of 3 as powers of prime factors.

Here, number of 2's is 3, number of 3's is 3 and number of 13's is 1.

So we need to multiply another 13² to the factorization to make 2808 a perfect cube.

Hence, the smallest number by which 2808 must be multiplied to obtain a perfect cube is 13² =169.
