A)
[tex]( {5}^{2} )^{5} \times ( {5}^{4} ) ^{3} = {5}^{10} \times {5}^{12} = {5}^{22} [/tex]
B)
[tex]( {7}^{8} )^{3} \div ( {7}^{5} )^{4} = {7}^{24} \div {7}^{20} = {7}^{4} [/tex]
C)
[tex](( \frac{1}{2} )^{3} )^{4} \times (( \frac{1}{2} )^{5} ) ^{5} = ( \frac{1}{2} )^{12} \times (\frac{1}{2} )^{25} \\ ( \frac{1}{2} )^{37} [/tex]
D)
[tex](0.8^{6} )^{9} \div (0.8^{5} ) ^{3} = 0.8 ^{54} \div 0.8^{15} \\ 0.8 ^{39} [/tex]
Zadanie 9
[tex] \frac{(b^{6})^{6} \times b }{(b ^{5})^{5} } = \frac{b^{36} \times b }{b^{25} } = \frac{b^{37} }{b^{25} } = b ^{12} [/tex]
Odpowiedź C
