x-x-2-24-y-y-3-18-2y-3x-y-x-




Question Number 10172 by konen last updated on 28/Jan/17
x^x =2^(24)  , y^y =3^(18) ⇒((2y+3x)/(y−x))=?
$$\mathrm{x}^{\mathrm{x}} =\mathrm{2}^{\mathrm{24}} \:,\:\mathrm{y}^{\mathrm{y}} =\mathrm{3}^{\mathrm{18}} \Rightarrow\frac{\mathrm{2y}+\mathrm{3x}}{\mathrm{y}−\mathrm{x}}=? \\ $$

x^x =2^(24)   x^x =(2^3 )^8   x^x =8^8   x=8  y^y =3^(18)   y^y =(3^2 )^9   y^y =9^9   y=9  ((2y+3x)/(y−x))=((2×9+3×8)/(9−8))=42
$$\mathrm{x}^{\mathrm{x}} =\mathrm{2}^{\mathrm{24}} \\ $$$$\mathrm{x}^{\mathrm{x}} =\left(\mathrm{2}^{\mathrm{3}} \right)^{\mathrm{8}} \\ $$$$\mathrm{x}^{\mathrm{x}} =\mathrm{8}^{\mathrm{8}} \\ $$$$\mathrm{x}=\mathrm{8} \\ $$$$\mathrm{y}^{\mathrm{y}} =\mathrm{3}^{\mathrm{18}} \\ $$$$\mathrm{y}^{\mathrm{y}} =\left(\mathrm{3}^{\mathrm{2}} \right)^{\mathrm{9}} \\ $$$$\mathrm{y}^{\mathrm{y}} =\mathrm{9}^{\mathrm{9}} \\ $$$$\mathrm{y}=\mathrm{9} \\ $$$$\frac{\mathrm{2y}+\mathrm{3x}}{\mathrm{y}−\mathrm{x}}=\frac{\mathrm{2}×\mathrm{9}+\mathrm{3}×\mathrm{8}}{\mathrm{9}−\mathrm{8}}=\mathrm{42} \\ $$
