ab x ac = ab - ac
If the numbers that are squared are odd, then the squared number will be odd. For example: 32 = 9 72 = 49 172 = 289 132 = 169 212 = 441 And all even numbers that are squared result in an even number. For example: 22 = 4 82 = 64 102 = 100 282 = 784 302 = 900
By definition, i^2=-1 Which also means: i=sqrt(-1) This may seem odd that such a number can be, since you may notice that all normal numbers, when squared, result in a positive number (e.g. (-3)^2=9, 0^2=0, 2^2=4). These "normal" numbers are called real numbers. Numbers that result in a negative number when squared are called "imaginary numbers". They don't lie on the real number line. i is the imaginary unit, just like 1 is the real unit. Don't let the names confuse you, imaginary numbers can be just as real and useful as real numbers, that's just a name that stuck with them.

16 is 4 squared, so lower square numbers would be the result of 1,2 or 3 squared. 1 squared is 1. 2 squared is 4. 3 squared is 9. So 1, 4, and 9 are all possible answers which fit the condition "a square number less than 16."
it is 18 because when you put all the numbers back into the square root it becomes the square root of 18 and the square root of 18 squared would be 18
When you square a number, the final digit is the final digit of the 'one's' number squared. Since the only single digit numbers squared which ends in 6 are 4 and 6, the answer is either 4 or 6 (a calculator tells me it is 6) 0 squared is 0. All numbers ending in 0 when squared will end in 0. 1 squared is 1. All numbers ending in 1 when squared will also end in 1. 2 squared is 4. All numbers ending in 2 when squared will end in 4. 3 squared is 9. All numbers ending in 3 when squared will end in 9. 4 squared is 16. All numbers ending in 4 when squared will end in 6. 5 squared is 25. All numbers ending in 5 when squared will end in 5. 6 squared is 36. All numbers ending in 6 when squared will end in 6. 7 squared is 49. All numbers ending in 7 when squared will end in 9. 8 squared is 64. All numbers ending in 8 when squared will end in 4. 9 squared is 81. All numbers ending in 9 when squared will end in 1. So square numbers can only end with 0, 1, 4, 5, 6 or 9.

It is impossible to list all squared prime numbers as there is an infinite number of squared prime numbers starting with 4, 9, 25, 49, 121, 169, 289, 361, 529, 841,...
There are an infinity of numbers and each one has its square...
(-1)2=1 all squared numbers turn out positive and 12=1 (-1)2=1 all squared numbers turn out positive and 12=1
Yes. Except for square of 1.
Yes.
