Algebra.Com's Answer #64173 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Given: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "First, note that all the bases are 7, so the rules that depend on the bases being common can \n" ); document.write( "be used. \n" ); document.write( ". \n" ); document.write( "Next note that two of the terms have exponents. The applicable rule for this this is: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "for the term \n" ); document.write( "these values into the rule results in: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Similarly, the other term of the original problem that also can be simplified using the \n" ); document.write( "power rule is: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "For this term x = 7, a = (4 - 6n), and b = 3. Substituting these values into the power rule \n" ); document.write( "results in: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Substituting the two simplifications into the original given problem results in it becoming: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Now you can apply the rule for two terms of a common base, each term raised to an exponent, \n" ); document.write( "when the two terms are multiplied. This rule states that the product is the common base \n" ); document.write( "raised to the sum of the exponents. In equation form this is: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "On the left side of the equation we have developed there are two terms that are multiplied. \n" ); document.write( "In this product x = 7, a = 4n - 5, and b = 6n + 9. When you substitute these values into \n" ); document.write( "the left side of the equation you get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "This becomes the left side of the equation. The equation becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Note that since the bases on the left and right sides are both the same ... 7 ... for \n" ); document.write( "the equation to be true, the two exponents have to be the same. So therefore you can say: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "We can solve this equation by getting all the terms containing n on one side of the equation \n" ); document.write( "and all the terms that are just numbers on the other side. Start by adding +24n to both sides. \n" ); document.write( "this makes the equation become: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "combining the terms containing n reduces the equation to: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Next add -4 to both sides to eliminate the +4 on the left side. This makes the equation: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Finally, solve for n by dividing both sides by 34 to get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Hope this helps you to see your way through the problem. \n" ); document.write( " |
