Prime factorising 108, we get,
Prime factorising 108, we get,108=3×3×3×2×2
Prime factorising 108, we get,108=3×3×3×2×2 =3 3 ×2 2
Prime factorising 108, we get,108=3×3×3×2×2 =3 3 ×2 2 .
Prime factorising 108, we get,108=3×3×3×2×2 =3 3 ×2 2 .We know, a perfect cube has multiples of 3 as powers of prime factors.
Prime factorising 108, we get,108=3×3×3×2×2 =3 3 ×2 2 .We know, a perfect cube has multiples of 3 as powers of prime factors.Here, number of 3's is 3 and number of 2's is 2.
Prime factorising 108, we get,108=3×3×3×2×2 =3 3 ×2 2 .We know, a perfect cube has multiples of 3 as powers of prime factors.Here, number of 3's is 3 and number of 2's is 2.So we need to multiply another 2 to the factorization to make 108 a perfect cube.
