What is the perfect number?
perfect number, a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3. Other perfect numbers are 28, 496, and 8,128. The discovery of such numbers is lost in prehistory.
Is 1 a perfect square?
So here if we multiply 1 by 1 i.e 1 × 1 = 1 itself the 1 as whole number, so Yes 1 is a perfect square, whenever we multiply the number by itself we will get a perfect square.
Do numbers end?
The sequence of natural numbers never ends, and is infinite. OK, 1/3 is a finite number (it is not infinite). There’s no reason why the 3s should ever stop: they repeat infinitely. So, when we see a number like “0.999…” (i.e. a decimal number with an infinite series of 9s), there is no end to the number of 9s.
