Xy, for, x=3 and y = 5

5a + b, for a = 6 and b = 3

6x, for x = 3

Step-by-step explanation:

Given problem;

i. xy, for x = 3 and y = 5

Insert the given parameters and solve;

   xy = 3 x 5 = 15

ii. 5a + b, for a = 6 and b = 3,

Insert the given parameters and solve;

  5(6) + 3  = 30 + 3 = 33

iii. 6x, for x  = 3

Insert the given parameters;

   6 x 3 = 18
