#1**+1 **

(5/3)^{-2}

A negative exponent means to move the term to the denominator and get rid of the negative sign.

= \(\frac{1}{(5/3)^{2}}\)

That is the same thing as:

= \(\frac{1}{5^{2}/3^{2}}\)

=\(\frac{1}{25/9}\)

=\(1 / \frac{25}{9}\)

Keep, change, flip

=\(1 * \frac{9}{25}\)

=\(\frac{9}{25}\)
