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
22 x 2 x 2 = 4 x 2 = 88 is a cube number = a number made by multiplying the same number by itself three times
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.
