Find the smallest value of k such that 3240k is a perfect cube

225

Step-by-step explanation:

3240k = 2×2×2×3×3×3×3×5×k

Every factor should be in groups of 3

(3×5)² = k

k = 225

Step-by-step explanation:

Prime factorize 3240

3240 = 2*2*2*3*3*3*3*5

To be a perfect cube we have to multiply it by 5*5*3*3 = 25*9=225

26?

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
