...........................

2.-140

Answer 2

To solve these expressions, we'll follow the order of operations, which states that multiplication and division should be performed before addition and subtraction. Let's solve each expression step by step:

1. (6 • (-2)) • 5: First, we'll simplify the expression within the parentheses: 6 • (-2) = -12 Now we can substitute this value back into the original expression: (-12) • 5 = -60 Therefore, (6 • (-2)) • 5 equals -60.

2. 5 • (4 • (-7)): Again, we'll simplify the expression within the parentheses first: 4 • (-7) = -28 Now we can substitute this value back into the original expression: 5 • (-28) = -140 Therefore, 5 • (4 • (-7)) equals -140.

So, the answers are: (6 • (-2)) • 5 = -60 5 • (4 • (-7)) = -140
