15. Use evaluation tree to evaluate the following expression: (45-4*5)+(7*4-8)* (12/4 -4*2)) 16. Write the truth table for logical operators AND, OR, and Not. 17. Evaluate mathematical expression (3*4-5*2)+(30-5*3)*(12+3*8/2). 15. Use evaluation tree to evaluate the following expression: (45-4*5)+(7*4-8)* (12/4 -4*2)) 16.
