Which number in the monomial [tex]$215 x^{18} y^3 z^{21}$[/tex] needs to be changed?

A. 3
B. 18
C. 21
D. 215

Answer :

To determine which number in the monomial [tex]\(215 x^{18} y^3 z^{21}\)[/tex] needs to be changed, we need to understand what the question is asking.

The monomial [tex]\(215 x^{18} y^3 z^{21}\)[/tex] consists of four specific numbers:
- The coefficient [tex]\(215\)[/tex], and
- The exponents [tex]\(18\)[/tex], [tex]\(3\)[/tex], and [tex]\(21\)[/tex] for variables [tex]\(x\)[/tex], [tex]\(y\)[/tex], and [tex]\(z\)[/tex] respectively.

The question seems to imply that one of these numbers might be incorrect. However, without additional context or information (such as an expected or standard form for comparison), there is no clear indication of which number needs to be changed.

In the absence of specific instructions or known criteria saying one of these numbers is wrong, we cannot determine which number needs to be changed based only on the information provided.

Thus, the conclusion is that there is no basis to change any of these numbers from their given values without further details. If there is no problem or error indicated, we assume each number stands as it is. Therefore, no number in the monomial needs to be changed without additional information.
