the answer is 1. there is only 1 perfect square beteen 30 and 40.
No - forty is not a perfect number. A perfect number is a number equal to the sum of all its factors apart from itself. The closest perfect numbers to 40 in each direction are: lower: 28 higher: 496
6 and 28
1, 4, 9, 16, 25, 36. These are the perfect squares from 1 to 40.
6, 28, 496, 8128.
11
The two perfect numbers less than 40 are 6 (1+2+3) and 28 (1+2+4+7+14).
The prime numbers from 0 to 40 are 2 3 5 7 11 13 17 19 23 29 31 37
Numbers with square roots that are whole numbers are called perfect squares. Examples of perfect squares include 0, 1, 4, 9, 16, and so on, as their square roots (0, 1, 2, 3, 4) are also whole numbers. Perfect squares arise from multiplying an integer by itself.
0, 1 and 64 are three numbers that qualify.
Any number squared except 0 is a perfect square so it follows that prime numbers are less common than perfect squares.
To find five numbers that equal -200, you can choose a combination of negative and positive numbers. For example, you could use -50, -50, -50, -50, and -0 to achieve the sum: -50 + -50 + -50 + -50 + 0 = -200. Alternatively, you could use -40, -40, -40, -40, and -40, which totals -200 as well.
