Answer:
18
Step-by-step explanation:
the smallest number by which 17496 must be divided ,so that the quotient is a perfect cube
let smallest number be x
and quotient number be y³
3 so, 17496/x which gives O as remainder and y³ as quotient
so, factors of 17496 = 2×2×2×3×3×3×3×3×3×3
no of 2's are 3 no of 3's are 7
so, factors of 17496 = 2³ × 3³ × 3³ × 3 = (2 × 3 × 3)³ × 3
so, smallest number is x = 3
y³= (2x3x3)³ y = 18
the perfect cube is y³ = 18³ cube root of 18³ = 18
