Final answer:
The correct symbols to create a true mathematical statement for 1− 81 _ 181 _ 0 are × (multiply) and > (greater than), which translates to − 81 > 0.
Step-by-step explanation:
The question is asking which symbols could be used to make a mathematical statement true. Specifically, the question involves finding the correct operations and inequality symbols to complete the statement 1 − 81_ 181 _ 0. The symbols in mathematics are not just placeholders; they represent specific operations and relationships. In the case of forming hypotheses, we use symbols like <, >, or ≠ to denote the direction of the inequality. When solving equations or inequalities, the choice of operations and comparison symbols must lead to a true statement +, × (times), > (greater than), or < (less than).
Now, considering the statement in the question, we can say the correct symbols to make the following statement true are × (multiply) for the first placeholder and > (greater than) for the second placeholder, which corresponds to option b. Therefore, the completed statement is 1 × (\u2212 81) > (181 \u00d7 0), which simplifies to \u2212 81 > 0, which is a true statement since \u2212 81 is less than 0.
