Hello!
Since we are given the values of a = 18 and b = 4, we substitute the values of a and b into the given expression and solve. Remember to use PEMDAS!
A) ab - This problem is another way to write "a times b". So, we multiply 18 and 4 together to get the product.
18 · 4 = 72
B) a/b - In this problem, we are dividing 18 by 4.
18/4 = 4.5
C) a + b · b
18 + 4 · 4 (multiply)
18 + 16 = 34
D) a - b + (a · a)/b
18 - 4 + (18 · 18)/4 (simplify)
14 + (324)/4 (divide)
14 + 81 = 95
