why is 75 3/5 equal to (75 1/5)^3

Answer:
First you need to notice that the 1/5 inside the parens is an exponent, 75^1/5. Then, when you have an exponent inside parens raised to another exponent, you multiply, so you have 1/5 x 3, which is 1/5 x 3/1, which equals 3/5.
The exponent rule shows that the [tex]75^{\frac{3}{5} } =75^{(\frac{1}{5})^3 }[/tex]
We have to show that the
[tex]75^{\frac{3}{5} } =75^{(\frac{1}{5})^3 }[/tex]
Here we have to apply exponent rule
[tex](a^b)^c=a^bc ...where (a\geq 0)[/tex]
use the above exponent rule,
[tex]\frac{1}{5}(3)=\frac{3}{5}[/tex]
Therefore we get right side is,
[tex](75^\frac{1}{5} )^3=75^\frac{3}{5}[/tex]
Therefore we get,
[tex]75^{\frac{3}{5} } =75^{(\frac{1}{5})^3 }[/tex]
The exponent rule shows that the [tex]75^{\frac{3}{5} } =75^{(\frac{1}{5})^3 }[/tex]
