1.
[tex](\frac{20}{15} )^{2} =\frac{20^{2} }{15^{2} } =\frac{400}{225} =\frac{16}{9}[/tex]
2.
[tex]\frac{42^{7} }{42^{4} } =42^{7-4} =42^{3} =74088[/tex]
3.
[tex]\sqrt[3]{(\frac{3}{5})^{6} } =(\frac{3 }{5 })^{2} }=\frac{3^{2} }{5^{2} } =\frac{9}{25}[/tex]
4.
[tex]\sqrt[12]{(\frac{512}{125})^{4} } =\sqrt[3]{\frac{512}{125} } =\frac{8}{5}[/tex]
