What is cube root and square root?
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 ]
What number multiplied by itself 3 times is 125?
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.

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.
What is 7x7x7x7x7x7x7x7x7x7 in exponential form?
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.
