The commutative property states that the order in which you add or multiply numbers does not change the result. Specifically:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Commutative property of multiplication<\/strong>: a\u00d7b=b\u00d7aa \\times b = b \\times aa\u00d7b=b\u00d7a<\/li>\n<\/ol>\n\n\n\n<p>Given this, let&#8217;s look at the expression pqpqpq. According to the commutative property, we can rewrite this as qpqpqp, since multiplication is commutative. Therefore:pq=qppq = qppq=qp<\/p>\n\n\n\n<p>Now, let\u2019s move on to the second part of the question: simplifying \u22129(\u22123)-9(-3)\u22129(\u22123).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Understanding multiplication of negative numbers<\/h3>\n\n\n\n<p>When multiplying two negative numbers, the result will be positive. This is because a negative times a negative equals a positive. Therefore:\u22129\u00d7\u22123=27-9 \\times -3 = 27\u22129\u00d7\u22123=27<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Detailed explanation<\/h3>\n\n\n\n<p>Multiplying negative numbers works because of the rules for signs in arithmetic:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When multiplying two <strong>positive<\/strong> numbers, the result is positive.<\/li>\n\n\n\n<li>When multiplying a <strong>positive<\/strong> and a <strong>negative<\/strong> number, the result is negative.<\/li>\n\n\n\n<li>When multiplying two <strong>negative<\/strong> numbers, the result is positive.<\/li>\n<\/ul>\n\n\n\n<p>In this case, we are multiplying two negative numbers: \u22129-9\u22129 and \u22123-3\u22123. According to the rule above, the result will be positive. The product is 272727.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Final answer:<\/h3>\n\n\n\n<p>\u22129(\u22123)=27-9(-3) = 27\u22129(\u22123)=27<\/p>\n\n\n\n<p>By applying the commutative property to the expression pqpqpq, we know that it can be written as qpqpqp, but the numerical simplification of \u22129(\u22123)-9(-3)\u22129(\u22123) is 27.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-1073.jpeg\" alt=\"\" class=\"wp-image-247985\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>use a commutative law to find an equivalent expression pq. an equivalent expression pq is= subtract the following -9(-3)= The Correct Answer and Explanation is: To apply the commutative law to simplify the expression pqpqpq, we first need to define what the commutative property is.
