How many integers in the set of all integers from 1 to 100, inclusive are not the square of an integer?

Answer 1

the only integers from 1 to 100 that are the square of another number are 1,4,9,16,25,36,49,64, 81 and 100.

the rest are not.

so, ten are squares and 90 are not.

Answer 2

The squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 (10 of them)
so there are 90 integers left from the 100

Answer 3

lemme see

there are 100 integers in the set

squares are: 9, 16, 25, 36, 49, 64, 81, 100

So 100 - 8 = 92 non-squares


Oooh! I suppose 1 is a square too

91 non-squares

Answer 4

All numbers are either squares or NOT.
So, the number of squares plus non-squares is 100
It is easier to count the squares. 10 of them!

ok.. take the squares away 1^2, 2^2, ... 10^2 , etc.
There are 100 numbers, the ten squares will be omitted.
So there are 90 total non-squares

Answer 5

90
