How many numbers between 1 and 1 000 000 are perfect squares but not perfect cubes?

990
In order for a number to be a perfect square and a perfect cube, the sixth power of the number needs to be less than 1,000,000. There are ten such numbers 1, 64, 729, 4,096, 15,625, 46,656, 117,649, 262,144, 531,441, and 1,000,000. Therefore there are 990 perfect squares that are not perfect cubes.

Which integer is a perfect square as well as a perfect cube?

Explanation − 1 and 64 are only numbers from 1 to 100 that are both perfect squares and cubes.

Is the number 1 000 a perfect square?

1000 is not a perfect square.

Which numbers are squares and cubes?

A square number is a number multiplied by itself. The square numbers up to 100 are: 0, 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100. A cube number is a number multiplied by itself 3 times. The cube numbers up to 100 are: 1, 8, 27 and 64.

What are the perfect squares from 1 to 30?

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 2, 5, 8, 10, 13, 17, 18, 20, 25, 26, 29, 32, 50, 65, 85, 125, 130, 145, 170, 185, 200, 3, 6, 9, 11, 12, 14, 17, 18, 19, 21, 22, 24.

What is a perfect square number example?

In mathematics, a square number, sometimes also called a perfect square, is an integer that is the square of an integer. For example, 25 is a square number, since it can be written as 5 × 5. What are the first n square numbers list?

What is the difference between a perfect square and a perfect cube?

If NNN is an integer, then N2N^2N2 is a perfect square. Because of this definition, perfect squares are always non-negative. Similarly, a perfect cube is an integer that can be expressed as the product of three equal integers. For example, 272727 is a perfect cube because it is equal to 3×3×3.3\imes 3 \imes 3.3×3×3.

What should be multiplied to make 600 a perfect cube?

The number 600 is not a perfect cube as all the prime factors is not a multiple of three. Question 2: What should be multiplied to the number 120 to make it a perfect cube? The factor 2 occurs thrice, 3 and 5 occurs only once. So in order to make it a perfect cube we have to multiply 120 with a square of 3 and 5.

Why are perfect squares always non-negative?

Because of this definition, perfect squares are always non-negative. Similarly, a perfect cube is an integer that can be expressed as the product of three equal integers. For example, 3 × 3 × 3. 3 imes 3 imes 3. 3×3×3. Determining if a number is a perfect square, cube, or higher power can be determined from the prime factorization of the number.
