The difference between the square root of x and squared-?
Answer: The difference between the square root of x and squared is either x or -x. Answer: The square root is the inverse function of the square function. That means that it's basically the opposite. Asking for the square root of "x" is like asking "what number must I square to get 'x'".
What is the difference between principal square root and perfect square root?
A principal square root is any square root that's answer is positive, and a perfect square root is a square root that's answer is an integer.
What is the number that it's cubic root of its square root equals its square root of its cubic root?
That would be a number to the 6th power, like 64.
How are fractional exponents and radicals are related?
Here are some examples. x1/2 = square root of x; x1/3 = cubic root of x; in general, x1/n = nth root of x. Also, x2/3 = the square of the cubic root of x, or equivalently, the cubic root of the square of x.
The difference between variance and standard deviation?
The SD is the (positive) square root of the variance.
