To rewrite the expression [tex]\(\left(\frac{2}{5}\right) x^5 y^5 z^7\)[/tex] using only positive exponents, we can follow these steps:
1. First, identify the original expression:
[tex]\[
\left(\frac{2}{5}\right) x^5 y^5 z^7
\][/tex]
2. Review the exponents involved in the terms [tex]\(x^5\)[/tex], [tex]\(y^5\)[/tex], and [tex]\(z^7\)[/tex]. Notice that all of these exponents are already positive.
3. Since all the exponents in the expression are positive, there is no need to make any alterations to the exponents.
4. The expression with positive exponents remains the same:
[tex]\[
\left(\frac{2}{5}\right) x^5 y^5 z^7
\][/tex]
Therefore, the expression using only positive exponents is:
[tex]\[
\left(\frac{2}{5}\right) x^5 y^5 z^7
\][/tex]
