Which of the following correctly represents the expression with a rational exponent?

A.

Step by step explanation:

We have been given an radical expression and we are asked to choose the correct option which represent our expression with a rational exponent.

Using exponent rule for negative exponents we can write our expression as:

Using the exponent property we can write our expression as:

Using exponent property we can write our expression as:

Therefore, after representing our expression with rational exponent our given expression will be: and option a is the correct choice.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
