Question $1$ Assume that T$($n$)=3$T$(($n$)/(2))+8^($log$\_(2)$n$).$ If $),$ what is c$+$k rounded to the nearest hundredth? $($If the Master Theorem cannot be used on this recurrence, use the answer $-1.)$ Question $2$ What is the sum of the real and imaginary parts of the product $(3+2$i$)(5-$i$)?$ Question $3$ Given matrices of the following sizes, determine the minimum number of single$-$register multiplications for the optimal parenthesization for the product ABCD:A:$3\backslash$times $4,$B:$4\backslash$times $5,$C:$5\backslash$times $2,$D:$2\backslash$times $9$ can you show thorough work for these problems
