Answer:

we conclude that:

[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]

Step-by-step explanation:

Given the expression

[tex]9x^0y^{-3}[/tex]

Apply exponent rule:    [tex]a^{-b}=\frac{1}{a^b}[/tex]

[tex]\:9x^0y^{-3}=9\cdot \:\frac{1}{y^3}x^0[/tex]

Apply rule:   [tex]a^0=1,\:a\ne \:0[/tex]

             [tex]=9\cdot \:1\cdot \frac{1}{y^3}[/tex]

Multiply fractions:   [tex]a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]

              [tex]=1\cdot \frac{1\cdot \:9}{y^3}[/tex]

Refine

               [tex]=\frac{9}{y^3}[/tex]

Thus, we conclude that:

[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]
