\( - \frac{4}{3}.\)

\(\frac{4}{3}.\)

\(\frac{3}{4}.\)

\( - \frac{3}{4}.\)

\({\left( {\frac{3}{2}} \right)^2}.{\left( {\frac{3}{2}} \right)^3} = {\left( {\frac{3}{2}} \right)^6}.\)

\({\left[ {{{\left( {\frac{3}{2}} \right)}^2}} \right]^3} = {\left( {\frac{3}{2}} \right)^6}.\)

\({\left( {\frac{3}{2}} \right)^7} = \frac{{{3^7}}}{{{2^7}}}.\)

\({\left( {\frac{3}{2}} \right)^3}:{\left( {\frac{3}{2}} \right)^2} = \frac{3}{2}.\)

\(\frac{7}{2}.\)

\(\frac{3}{{15}}.\)

\(\frac{{19}}{4}.\)

\(\frac{{24}}{{18}}.\)

\(8.\)

\(0.\)

\( - 8.\)

\(4.\)

\(0,3.\)

\( - 1,\left( 1 \right).\)

\(\sqrt 5 .\)

\(\sqrt 4 .\)

\(a.d = b.c.\)

\(a + d = b + c.\)

\(a.c = b.d.\)

\(a:d = c:b.\)

\(\frac{a}{2} = \frac{b}{3} = \frac{c}{5}.\)

\(\frac{a}{5} = \frac{b}{3} = \frac{c}{2}.\)

\(\frac{a}{3} = \frac{b}{5} = \frac{c}{2}.\)

\(\frac{a}{2} = \frac{b}{5} = \frac{c}{3}.\)

\(y = \frac{1}{4}x.\)

\(y = - 4x.\)

\(x = - 4y.\)

\(y = \frac{{ - 4}}{x}.\)
