The opposite of a square root (exponent 1/2) is the square (exponent 2).
The number 21 can be written as 2.10 × 101
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.
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 (exponent 1/2) is the square (exponent 2).
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.
The number 21 can be written as 2.10 × 101
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.
Fifty squared written in exponent form is 502
