Without looking it up, I believe it comes from the fact that if you have a square, and it's, say 2 units long and 2 units wide, the area of the square is 4 square units. (if it was 2 ft x 2 ft then area is 4 square feet). 2 x 2 is the same as 22
Likewise to find a volume of a cube, multiply length by width by height. Since they are all the same, you have (side)3 is the volume. Something to the third power is called 'cubed'. Since we live in a three dimensional world, as far as we know, nobody has come up with a term for fourth power, fifth power, etc.
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
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
yes it is 2 to the second power is equal to 4
3x2 can be called "three times x squared", "three x squared", or "three times x to the power of two".
1/4 (1/2) squared = 1/2 x 1/2 = 1/4
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
It is about: 1.4142135622 squared = 2
8x to the second power times 3x to the second power (8x)2 + (3x)2 = 64x2 + 9x2 = 73x2 is one possibility, except the problem called for multiplication which would make the answer 64x squared times 9x squared = 576x to the fourth power It could also be read this way: 8x squared times 3x squared equals 24x to the fourth power. I wish my computer would do those cool little twos.
Sqaured. For example, 2 to the second power (2^2) coulld also be read as 2 squared.
X to the second power or x squared.
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
70 to the power of 2, or, 70 squared, is 70X70, which equals 4,900
2/3 squared is 4/9
A variable raised to the second power would be refered to as "squared." Some math-based programs like Excel let you enter a power with a carot, ie, "(variable name)^2" if you want to calculate the answer.
5/2 to the second power means 5/2 squared. "Squared" means multiplied by itself. We would write this as (5/2)2. This means (5/2) * (5/2). 5/2 * 5/2 = 25/4 = 6.25.
If you're talking about mathematics, then any number that is squared is a number that is multiplied by itself, or in other words, raised to second power. For example: 6 squared is the same as 6 times 6 and the same as 6 to the second power or 6 to the power of 2 (6^2).
yes it is 2 to the second power is equal to 4
