Writing it as: 1, 4, 9, 1 6, 2 5, 3 6, 4 9, 6 4, 8 1, ... Should help you spot it is the digits of the square numbers written out in order.
Squaring is the function used when we multiply a number by itself. The number you are multiplying is called the baseand the exponent 2 indicates you are multiplying the base by itself. base2 = base x base = square Squaring is the function used when we multiply a number by itself.

11 squared is 121
No. Think 13, 22, 31 for a start!
4, 400, 40000 etc 121, 12100, 1210000 etc
How about 7*7 = 49 because 4+9 = 13

It is a factor of 32, which means it is one of 1, 2, 4, 8, 16, and 32. The perfect squares among the factors of 32 are 4 and 16. Of those two, the only one with a sum of digits that is odd is 16.
4*4=16 sum of 1+6 is 7, difference is 5 so 16 is answer
16
Well, let's see. Perfect cubes that are two digits: 27 64 Could it be 27? Well, 2+7 is 9, and that's a perfect square with a square root of 3, and the cube root of 27 is three. Looks like we've found our answer, especially since 6+4 = 10, which is NOT a perfect square.

the perfect square of 4 is 16
No. 26 for instance the sum of the digits is 8 but not divisible by 4. 32 the sum of the digits is 5 but divisible by 4 The rules for some other numbers are 2 all even numbers are divisible by 2 3 The sum of the digits is divisible by 3 4 The last 2 numbers are divisible by 4 5 The number ends in a 0 or 5 6 The sum of the digits is divisible by 3 and is even 7 no easy method 8 The last 3 numbers are divisible by 8 9 The sum of the digits is divisible by 9
