The expression that does not belong to the other group of expression is (c) 7(-2)(-5)

<h3>What are expressions?</h3>

Expressions are mathematical statements that are represented by numbers and/or variables

The expressions are given as:

  • 5(−3)(−1)
  • (−4)2(−6)(−2)
  • 7(−2)(5)
  • −20(−6)

Start by evaluating all 4 expressions

5(-3)(-1) = 15

(-4)^2(-6)(-2) =192

7(-2)(5) = -70

-20(-6) = 120

Notice that three of the expressions return a positive result, while one of them return a negative result

The negative expression is the odd one among the four expressions

Hence, the expression that does not belong is (c) 7(-2)(-5)
