a)
[tex] \frac{ {5}^{7} \times {5}^{0} \times 5 }{ {5}^{3} } = \frac{ {5}^{8} }{ {5}^{3} } = {5}^{5} [/tex]
b)
[tex] {0.9}^{6} \times { {((0.9)}^{2}) }^{4} \div {0.9}^{5} = {0.9}^{6} \times {0.9}^{8} \div {0.9}^{5} = {0.9}^{14} \div {0.9}^{5} = {0.9}^{9} [/tex]
c)
[tex] \frac{ { {(a}^{5}) }^{3} \times {a}^{0} \times {a}^{15} }{ {a}^{20} \div {a}^{10} } = \frac{ {a}^{15} \times {a}^{0} \times {a}^{15} }{ {a}^{10} } = \frac{ {a}^{30} }{ {a}^{10} } = {a}^{20} [/tex]
d)
[tex] \frac{ { {(x}^{0} )}^{7} \times { {(x}^{17}) }^{0} }{ {(( { {x}^{17} )}^{2} \div {x}^{17} )}^{0} } = \frac{ {x}^{0} \times {x}^{0} }{ {( {x}^{34} \div {x}^{17} )}^{0} } = \frac{ {x}^{0} }{ { {(x}^{17} )}^{0} } = \frac{ {x}^{0} }{ {x}^{0} } = {x}^{0} [/tex]
