$(30\text{'})$ Write a code which uses $x$ value in $R1$ and returns the result value of the following function: $f(x)=2^x+3^x$ into R$0.$ Assume that $x$ is within the range of $010.$ Use the look$-$up table method and use the subroutine approach. The values for $2^x$ and $3^x$ are listed in the tables below.

$\backslash$table$[[x,0,1,2,3,4,5,6,7,8,9,10],[2^x,1,2,4,8,16,32,64,128,256,512,1,024]]$

$\backslash$table$[[x,0,1,2,3,4,5,6,7,8,9,10],[3^x,1,3,9,27,81,243,729,2,187,6,561,19,683,59,049]]$
