Perfect squares are positive.
A smallest negative number doesn't exist.
The four smallest prime numbers are 2, 3, 5 and 7.
The smallest perfect square would have to be 2^2 x 3^2 x 5^2 x 7^2 or 44,100
For a positive number, just multiply the squares of the first four prime numbers. I am not entirely sure what you mean with "negative perfect square"; pressumably, you just need to add a minus sign. But note that negative numbers cannot be the squares - perfect or otherwise - of real numbers. The square root of negative numbers is a complex number.
44,100
(3x5x7x11)2 =1334025
44,100
It is 49.
6 and 28.
yes
hello my name is jack
3600 is the smallest perfect square divisible by 8,9 and 10. Work out the prime factorisations for each of the numbers 8, 9, 10: 8 = 23 9 = 32 10 = 2 x 5 So the perfect square must be a multiple of the lcm of 8, 9 & 10 = 23 x 32 x 5 to be divisible by all three numbers. All perfect squares have even powers for all their primes (in their prime factorisation), so to make all the powers even the smallest multiplier of this is 2 x 5, giving 24 x 32 x 52 = 3600.
360
the smallest perfect number is 1
the answer is 144, it is divisible by 1, 4, 9, 16, 36, and 144.
25 = 9 + 16 There are many more sets like these. This one has the smallest numbers.
