The answer is 7. Because 7X7=49 then 49-7= 42!
No number times itself can give the result of -144 .Any number has the same sign as itself has, and whenever you multiplytwo numbers that have the same sign, the result is a positive number.
Same as multiplying any number by itself once or many times.
to the second power, or times itself
Itself because 1 times a number = the same number
No, because the square of a number is that number times itself, so a no two numbers will have the same square.
it is the same with any number. 2 is in the 2 times table (1x2)
Times it again by the same number [e.g] square of 4 is 4X4=16 so square of 4 is 16
That's because you are multiplying it by itself. So "two, squared' means the same as 'two times two', and 'three, squared' means the same as 'three times three'. Multiplying a number by itself is exactly the same process of finding the area of a square who's dimensions are the number in question. Therefore multiplying a number by itself is known as squaring. For the same reason of raising a number to the third power is known as cubing. (Because its the same process you would use to find the volume of a cube.)
Any number divided by itself is the same as ' 1 '.
The phrase "square of a number" means the number times itself. For example, the square of 5 is 25. This is the same as saying the number "squared".
No, because 1 times itself is one, making it not a square number. It has to equal a different number than the number times itself. * * * * * A totally incorrect answer - on two counts. (a) a square number does not have to be different and, (b) even if that were the case, 1 is the square of -1 and -1 is not the same as 1.
No, because 1 times any number is an axiom, or law, of math; The identity axiom of multiplication, that states any number that is a real number multiplied by 1 equals itself. ex. a x 1 = a, a = 5 5 x 1 = 5 Results will be the same for any real number.
