4 × (-5) = (-10) × (- 2)
Solution:
The requirement of the above question is to prove whether the given statement is true or false.
The given expression is 4 × (-5) = (-10) × (- 2).
Now let us put the integer rules and solve the LHS and RHS part
4 × (-5) = (-10) × (- 2)
-20 ≠ 20
Therefore, using the integer rules, we observed that 4 × (-5) = (-10) × (- 2) is a false statement.
✦ Try This: State whether the statement is true or false. 6 × (-5) = (-10) × (- 3).
We can apply integer rules and the order of operations to identify whether 6 × (-5) = (-10) × (- 3) true or false.
