Witam.
[tex]a) \: \frac{ {3}^{4} \times 3^{5} }{ {3}^{7} } = \frac{ {3}^{9} }{ {3}^{7} } = {3}^{9} \div {3}^{7} = {3}^{2} [/tex]=9
[tex]b) \: \frac{ {4}^{5} \times {4}^{7} }{ {4}^{6} \times {4}^{4} } = \frac{4 ^{12} }{ {4}^{10} } = {4}^{12} \div {4}^{10} = {4}^{2} [/tex]=16
[tex]c) \: \frac{ {5}^{8} \div {5}^{5} }{ {5}^{2} } = \frac{ {5}^{3} }{ {5}^{2} } = {5}^{3} \div {5}^{2} = 5[/tex]
[tex]d) \: \frac{ {6}^{12} \times 6 }{ {6}^{8} \times {6}^{3} } = \frac{ {6}^{13} }{ {6}^{11} } = {6}^{13} \div {6}^{11} = {6}^{2} [/tex]=36
Pozdrawiam,
Michał
