Question
( 2^{x}left(2^{2}-2^{3}-2^{4}right)>5^{x}left(5-5^{2}right) )
2) ( 2^{x}(4-8-16)>5^{x}(5-25) )
( Rightarrow 2^{x}(-20)>5^{x}(-20) )
( Rightarrow quad-2^{x}>-5^{x} )
( Rightarrow quad Rightarrow quad 2^{x}<5^{x} )
( Rightarrowleft(frac{5}{2}right)^{x}>1 Rightarrowleft(frac{5}{2}right)^{x}>left(frac{5}{2}right)^{0} )
