This is related to the calculation of the area of a square: area = side x side = side2.
Taking a number to the second power is known as "squaring" the number.
That is also called "squaring the number", or "raising the number to the second power".
Raising a number to the second power means you are squaring the number, multiplying it by itself. 2 squared= 2*2=4 3 squared=3*3=9
squaring a number is taking it to the second power, initialy just multiplying it by its self.
multiply the number by itselfRaising a number to the second power means you are squaring the number, multiplying it by itself. 2 squared= 2*2=43 squared=3*3=9
49."To the second power" means that the number is multiplied by itself once.We also refer to this as "squaring" or that a number has been "squared".7 * 7 = 49.
Multiplying a number by its self is called squaring a number When using exponents, the second power of a whole number is called a perfect square too, For example, write 4 squared = 16, 7 squared = 49, and 265 = 70, 225 are all perfect squares.
To write powers of a number you write the number, followed by the number of the power in superscript. For example, a number to the second power is x2, a number to the third power is x3 and so on. Squaring is taking a number to the second power. Thus 20 squared is 202, which equals 400.
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.)
In that event, the first number is called a "multiple" of the second number.
YES Any rational number taken to any integer power is still rational. Now if you meant to refer to the irrational number Pi - which is approximately 3.14159..., then squaring it does not make it rational.
The first number is divisible by the second number
