Odpowiedź:
a)
[tex]( {5}^{4} ) ^{7} = {5}^{28} [/tex]
b)
[tex] {7}^{15} \div {7}^{9} = {7}^{6} [/tex]
c)
[tex] {3}^{12} \times {3}^{9} = {3}^{21} [/tex]
d)
[tex] \frac{ {6}^{10} \times {6}^{12} }{( {6}^{5})^{4} } = \frac{ {6}^{22} }{ {6}^{20} } = {6}^{2} [/tex]
e)
[tex] {8}^{4} \div {2}^{7} = ( {2}^{3} ) ^{4} \div {2}^{7} = {2}^{12} \div {2}^{7} = {2}^{5} [/tex]
f)
[tex]81 \times ( {3}^{6} ) ^{4} = {3}^{4} \times {3}^{24} = {3}^{28} [/tex]
g)
[tex] {16}^{7} \div {8}^{7} = (16 \div 8) {}^{7} = {2}^{7} [/tex]
h)
[tex] \frac{( {5}^{6} ) {}^{4} \times {16}^{5} }{ {125}^{7} \times ( {2}^{3}) {}^{4} } = \frac{ {5}^{24} \times ( {2}^{4} ) {}^{5} }{( {5}^{3}) {}^{7} \times {2}^{12} } = \frac{ {5}^{24} \times {2}^{20} }{ {5}^{21} \times {2}^{12} } = {5}^{3} \times {2}^{8} [/tex]
