zadanie 3
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]
4 nie wiem, sorry
