When you take the square root of a variable with an even number exponent how does the exponent value change?
When you take the square root of a variable raised to an exponent, you divide the exponent by two. For example the square root of x^4 is x^2, because x^2 x x^2 =x^4.
What is the exponent form for 21?
The exponent form for 21 is 21^1. In exponent form, the base number (21) is raised to the power of 1. This means that 21^1 equals 21. Exponentiation is a mathematical operation that represents repeated multiplication of the base number by itself the number of times indicated by the exponent.
What is exponents square root?
The exponent for a square root is 0.5 or 1/2.
What is half an exponent mean?
I assume the question is about an exponent whose value is a half (or a multiple of a half). An exponent of a half is simply the square root. Similarly, an exponent of (1/3) is a cubed-root and so on.
Is the square root an exponent?
Yes, the square root is equivalent to an exponent of 1/2.Suppose the exponent is a rational number of the form p/q where p and q are integers and q > 0. Then x^(p/q) = (the qth root of x) raised to the power p or, equivalently, (the qth root of (x raised to the power p).
