Find the $\backslash$beta $-$normal forms of the following $\backslash$lambda $-$expressions:

$1.$ S $($S K$)$

$2.2$ K$$

$3.$ S $($K K$)$ K$$

$4.$ S S I I

$5.$ K K$$ S S S

You should submit your answers in a PDF file generated using LaTeX. $($A LaTeX template will be either

emailed to you or uploaded on Brightspace.$)$ You only need to submit the final answers, i$.$e$.,$ the $\backslash$beta $-$normal

forms, in each case
