[tex]( {5}^{6} )^{12} \times {5}^{28} = {5}^{72} \times {5}^{28} = {5}^{72 + 28} = {5}^{100} [/tex]
[tex]( {5}^{16} )^{18} \div ( {5}^{32})^{9} = {5}^{288} \div {5}^{288} = {5}^{288 - 288} = {5}^{0} = 1[/tex]
[tex]( {2}^{11} )^{20} \times {2}^{200} = {2}^{220} \times {2}^{200} = {2}^{420} [/tex]
[tex]( {2}^{6} )^{4} \times ( {2}^{5} )^{3} \div ( {2}^{3} )^{12} = {2}^{24 + 15 - 36} = {2}^{3} = 8[/tex]
