Yes. In fact, they are integers.
Answer: 1, 64, & 729
The cube root of 5000 is approx 17.1 So the numbers 1 to 17 have cubes which are smaller than 5000 that is, there are 17 such numbers.
If you include fractions and decimals, then there are an infinite number of squares and cubes in any range. If you consider only whole numbers, then from 1 to 20: Squares: 1, 4, 9, and 16. Cubes: 1 and 8.
Usually they don't, unless you work in engineering.
64 is the square of 8 and the cube of 4.
Yes. In fact, they are integers.
Answer: 1, 64, & 729
there are no perfect numbers instead there are perfect cubes, perfect squares, natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers. If you want natural no. they are 21, 22, 23, 24, 25, 26, 27, 28, and 29.
no
Cubes of squares or squares of cubes, like 1, 64 and 729.
the three numbers that are less than 1000 and are perfect squares and perfect cubes are:1, 64, 7291 = 1 x 1 = 1 x 1 x 164 = 8 x 8 = 4 x 4 x 4729 = 27 x 27 = 9 x 9 x 9

Perfect cubes.

Not necessarily. The cube of sqrt(2) is not rational.
