Respuesta :
When you multiply an exponent directly to a fraction, you multiply the exponent to the top and bottom of the fraction.
For example:
[tex](\frac{2}{5} )^2[/tex] or [tex](\frac{2^1}{5^1} )^2=\frac{2^{(1*2)}}{5^{(1*2)}} =\frac{2^2}{5^2} =\frac{4}{25}[/tex]
[tex](\frac{x^2}{y^2})^3 =\frac{x^{(2*3)}}{y^{(2*3)}} =\frac{x^6}{y^6}[/tex]
[tex](\frac{4}{3})^3=\frac{4^{(1*3)}}{3^{(1*3)}} =\frac{4^3}{3^3}=\frac{64}{27}[/tex] (you can't simplify any further)
