[tex] { \frac{ {15}^{13} \div ( {5}^{4} \times {5}^{6} )}{ {5}^{2} } } = \frac{ {5}^{13} \div {5}^{10} }{ {5}^{2} } = \frac{ {5}^{3} }{ {5}^{2} } = {5}^{1} = 5[/tex]
Pozdrawiam :))
[tex]\frac{5^{13} : (5^{4}*5^{6}) }{5^{2} } = \frac{5^{13} :(5^{4+6}) }{5^{2} } = \frac{5^{13} : 5^{10} }{5^{2} } = \frac{5^{13-10} }{5^{2} } = \frac{5^{3} }{5^{2} } = 5^{3-2} = 5^{1} = 5[/tex]
