The expression that is equivalent to the given expression is 125y⁵.
The given expression is:
[tex]\frac{5y^{3} }{(5y)^{-2} }[/tex]
Some important power rules applicable to this problem are:
1)[tex](ab)^m=a^mb^m[/tex]
2)[tex]\frac{1}{a^{-n} } =a^n[/tex]
So, [tex]\frac{5y^{3} }{(5y)^{-2} } =\frac{5y^{3} }{5^{-2} y^{-2} }[/tex].....by power rule (1)
[tex]=(\frac{5}{5^{-2} } )(\frac{y^3}{y^{-2} })[/tex]
[tex]=5^3y^5[/tex].....by power rule(2)
[tex]=125y^5[/tex]
Hence, the expression that is equivalent to the given expression is 125y⁵.
