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.
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.
The exponent for a square root is 0.5 or 1/2.
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.
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).
That means that the exponent is a fraction, such as 21/2 = square root of 2, 101/3 = cubic root of 10, etc.
The opposite of a square root is the square of a number. In mathematical terms, if the square root of a number x is denoted as √x, then the opposite of the square root (√x) is x itself. This is because squaring a number undoes taking the square root of that number.
And exponent of -2 represents the square root
The relevant exponent is -2.
Cut the exponent in half.
take your number that will be effected by the exponent, and multiply it by itself how many times the exponent stands for so if you had 122 you would do 12 x 12 so if you had 215 you would do 21 x 21 x 21 x 21 x 21 to get 4084101
Any even exponent of 3 is a square number.
21 can be written as 2.10 × 101
The square of a number can be represented by writing the number with an exponent of 2, whereas the square root of the number is represented by writing the number with an exponent of 1/2.
