\\ \sf\longmapsto \dfrac{(0.0225)^{\frac{-3}{2}}\times (0.0001)^{\frac{3}{4}}}{(0.0125)^{\frac{1}{3}}}

\\ \sf\longmapsto \dfrac{((0.15)^2)^{\frac{-3}{2}}\times ((0.1)^4)^{\frac{3}{4}}}{(0.5)^3)^{\frac{1}{3}}}

\\ \sf\longmapsto \dfrac{(0.15)^{2\times \dfrac{-3}{2}}\times (0.1)^{4\times \dfrac{3}{4}}}{(0.5)^{3\times \dfrac{1}{3}}}

\\ \sf\longmapsto \dfrac{(0.15)^{-3}(0.1)^3}{(0.5)^1}

\\ \sf\longmapsto \dfrac{\dfrac{1}{(0.15)^3}\times 0.001}{0.5}

\\ \sf\longmapsto \dfrac{\dfrac{1}{0.003375}(0.001)}{0.5}

\\ \sf\longmapsto\dfrac{ \dfrac{1000000}{3375}\times \dfrac{1}{1000}}{0.5}

\\ \sf\longmapsto \dfrac{\dfrac{1000}{3375}}{0.5}

\\ \sf\longmapsto \dfrac{1000}{3375}\times \dfrac{10}{5}

\\ \sf\longmapsto \dfrac{2000}{3375}

\\ \sf\longmapsto 0.592

icang [17]

Step-by-step explanation:

first add 23 to both sides and get 10x=52-3x then add the 3 to the 10x and get 13x=52

then divide both sides by 13 and you should get x = 4
