The square root of 8 is approximately 2.828. However, if you're seeking a whole number solution, 8 doesn't have a perfect square root. Nevertheless, consider this: 2 squared (2²) equals 4, and when you multiply 4 by 2, you get 8.

Or in an even simpler form:

"The square root of 8 is about 2.828. If you're looking for whole numbers, try this: 2² = 4, and 4 × 2 = 8.

A square root of a number is a number that, multiplied by itself once, will equal the first number. Meanwhile a cube root of a number is a number that, multiplied by itself twice, will equal the first number. For example: the square root of 4 is 2. [ 2 X 2 = 4 ] [ 2 times itself equals 4 ] : the cube root of 8 is 2. [ 2 X 2 X 2 = 8 ] [ 2 times itself, and then times itself again, equals 4 ]

If x is the number, thenx multiplied by itself once is x*x,x multiplied by itself twice is x*x*x,x multiplied by itself three times is x*x*x*x,So it is the fourth root of 125 = 3.3437, approx.

The expanded form is 5*5*5. Remember, cubed means the number multiplied by itself twice times, and squared is the number multiplied by itself once, or 5*5.

A number, x, multiplied by itself once is x^2. It is NOT x.The number, x, multiplied by itself twice is then x^3.The number, x, multiplied by itself three times is then x^4.Thus x is the 4th root of 27.So x = 27^(1/4) = +/- 2.2795 and +/- 2.2795*i where i is the imaginary square root of -1.

In exponential form, 7 times itself 9 additional times (7x7x7x7x7x7x7x7x7x7) is: 710 To get the exponential form from the example above, start with 1 and add 1 for each additional repeat of the number being multiplied by itself. Once found, put a superscript of that number after the number being multiplied by itself. In the above situation, 7 was multiplied by itself a total of 9 times, so 9 + 1 = 10.

A number which is multiplied by itself once is said to be squared = 5 x 5 = 25, also written as 52. This is called a square because if the sides of a rectangle are the same, it is a square.A number which is multiplied by itself twice is said to be cubed = 5 x 5 x 5 = 125, also written as 53. This is called a cube because if the sides of a three-dimensional object with a square base are all the same it is a cube.

The definition of squaring a number is to multiply it by itself once.

Because a number will divide into itself once 1

Same as multiplying any number by itself once or many times.

Think of it this way...how many times can you divide a number by itself? The answer is always once. 4 divided by 4 equals 1. Using the number 4, 8 divided by 4 equals 2. In other words, 8 is equal to two 4s, right? But one 4 is always one 4.
