#### Explanation:

What I believe you mean is to express using only positive exponents.

To do this use the#color(blue)"law of exponents"#

#color(orange)"Reminder" color(red)(|bar(ul(color(white)(a/a)color(black)(a^-mhArr1/a^m)color(white)(a/a)|)))# The expression may now be written.

#5cd^-9=5/1xxc/1xx1/d^9=(5xxcxx1)/(1xx1xxd^9)=(5c)/d^9#
