If  x^(200)  < 3^(300)  , then greatest possible  integral value of   x  is _____.
$$\mathrm{If}\:\:{x}^{\mathrm{200}} \:<\:\mathrm{3}^{\mathrm{300}} \:,\:\mathrm{then}\:\mathrm{greatest}\:\mathrm{possible} \\ $$$$\mathrm{integral}\:\mathrm{value}\:\mathrm{of}\:\:\:{x}\:\:\mathrm{is}\:\_\_\_\_\_. \\ $$

x^(200) <3^(300)   (x^2 )^(100) <(3^3 )^(100)   x^2 <3^3 =27  x<(√(27))  x≤5  ⇒x_(max) =5
$${x}^{\mathrm{200}} <\mathrm{3}^{\mathrm{300}} \\ $$$$\left({x}^{\mathrm{2}} \right)^{\mathrm{100}} <\left(\mathrm{3}^{\mathrm{3}} \right)^{\mathrm{100}} \\ $$$${x}^{\mathrm{2}} <\mathrm{3}^{\mathrm{3}} =\mathrm{27} \\ $$$${x}<\sqrt{\mathrm{27}} \\ $$$${x}\leqslant\mathrm{5} \\ $$$$\Rightarrow{x}_{{max}} =\mathrm{5} \\ $$
