Odpowiedź:
a) 5⁸ : 5⁴ × 5² = 5⁴ × 5² = 5⁶
b) (0.4⁵)³ = 0.4¹⁵
c)
[tex] \frac{(9 {}^{2} ) {}^{4} \times 9 {}^{6} }{9 {}^{2} } = \frac{9 {}^{8} \times {9}^{6} }{ {9}^{2} } = \frac{ {9}^{14} }{ {9}^{2} } = {9}^{12} [/tex]
[tex]5^{8}:5^{4}\cdot 5^{2}=5^{4} \cdot 5^{2} = \boxed{5^{6} }\\\\\\(0,4^{5})^{3}= \boxed{ 0,4^{15}}\\\\\\\frac{(9^{2} )^{4}\cdot9^{6} }{9^{2}} =\frac{9^{8} \cdot9^{6} }{9^{2} }=\frac{9^{14} }{9^{2}} =\boxed{ 9^{12} }[/tex]
