$2\mathrm{.}1)1()=322()=38$

A: $1()=(2())$ B: $1()=\backslash$Omega $(2())$ C: $1()=\backslash$Theta $(2())$

$2\mathrm{.}2)1()=22()=38$

A: $1()=(2())$ B: $1()=\backslash$Omega $(2())$ C: $1()=\backslash$Theta $(2())$

$2\mathrm{.}3)1()=2()=(>=1>1)$

A: $1()=(2())$ B: $1()=\backslash$Omega $(2())$ C: $1()=\backslash$Theta $(2())$

$2\mathrm{.}4)1()=+50\mathrm{.}52()=32+5+1$

A: $1()=(2())$ B: $1()=\backslash$Omega $(2())$ C: $1()=\backslash$Theta $(2())$
