As you can see, the fraction 3/8 is multiplying 3 times by itself. Then we can write:
[tex]\frac{3}{8}\cdot\frac{3}{8}\cdot\frac{3}{8}=\mleft(\frac{3}{8}\mright)^3[/tex]And since it is a fraction, we can use the Power of a Quotient Property.
[tex]\mleft(\frac{a}{b}\mright)^m=\frac{a^m}{b^m}\Rightarrow\text{ Power of a Quotient Property}[/tex]So, we can also write:
[tex]\mleft(\frac{3}{8}\mright)^3=\frac{3^3}{8^3}[/tex]Therefore, if we write the given expression using exponents, we have:
[tex]\boldsymbol{\frac{3}{8}*\frac{3}{8}*\frac{3}{8}=}\mleft(\boldsymbol{\frac{3}{8}}\mright)^{\boldsymbol{3}}\boldsymbol{=\frac{3^3}{8^3}}[/tex]
