Find the smallest positive integer such that 360k is a cube number.

360=(2^3)(3^2)(5),to make it a cube no, all the factors of 360 must be in cubic form, 2 is already in cubic form, so 'k' is (3)(5^2) to make cubes of 3 n 5 as well :)

Find the frequency of each separate x value by the formula f=fd * class width. The value which has the highest frequency is your mode. For medium, you'll have to make a table. You need a CF column..

I understood the part that to make cubic number which 2 is already in cubic form.... But I dont get that part of k (3)(5^2), how r these made into cube numbers and u took 5^2?? :unsure:
