Answer 1

$5)0,16*(-10)^{2}-2^{2}=0,16*100-4=16-4=12\\\\6)\frac{(a^{7})^{3}*(x^{5})^{4}}{(a^{4})^{3}*(x^{8})^{2}}=\frac{a^{21}*x^{20}}{a^{12}*x^{16}}=a^{21-12}*x^{20-16}=a^{9}x^{4}\\\\7)\frac{a^{6}}{y^{12}}=a^{6}*y^{-12}\\\\8)4^{-1}x^{5}y^{-3}=\frac{x^{5}}{4y^{3}}\\\\9)x^{3}=-\frac{1}{27}\\\\x^{3}=(-\frac{1}{3})^{3} \\\\x=-\frac{1}{3}\\\\x^{4}=(-\frac{1}{3})^{4}=\frac{1}{81} \\\\10)\frac{5a^{10}-3a^{6}}{a^{5}}=\frac{a^{5}(5a^{5}-3a)}{a^{5}}=5a^{5}-3a$
