Answer: D. 6 3*/2x 2*
Explanation:
All of the answer choices you provided involve radicals, which are numbers or expressions that include a square root (or other root) symbol. In order to determine which answer choice is a like radical to the given radical (6 3*/2x), we must compare the coefficients, the indices, and the radicands of each radical.
The coefficient of a radical is the number that appears before the radical symbol, while the index is the number written as a small superscript to the right of the radical symbol. The radicand is the number or expression that is inside the radical symbol.
For the given radical (6 3*/2x), the coefficient is 6, the index is 3, and the radicand is 2x.
With this information in mind, we can compare the answer choices as follows:
A. 6 3*/x - This radical has the same coefficient and index as the given radical, but the radicand is different (it is x instead of 2x). Therefore, this is not a like radical to the given radical.
B. 6 4*/2x - This radical has the same coefficient and radicand as the given radical, but the index is different (it is 4 instead of 3). Therefore, this is not a like radical to the given radical.
C. -5 3*/2x - This radical has the same index and radicand as the given radical, but the coefficient is different (-5 instead of 6). Therefore, this is not a like radical to the given radical.
D. 6 3*/2x 2* - This radical has the same coefficient and index as the given radical, and the radicand is 2x, which is the same as the given radical. However, there is an additional exponent of 2 after the radical symbol, which is not present in the given radical. Therefore, this is not a like radical to the given radical.
Therefore, the correct answer is:
D. 6 3*/2x 2*
