Algebra.Com's Answer #421766 by jsmallt9(3758)![]() ![]() ![]() You can put this solution on YOUR website! First of all, is the equation \n" ); document.write( " \n" ); document.write( "or \n" ); document.write( " \n" ); document.write( "I think you meant the first one but what you entered meant the second one. If I'm right then please put parentheses around multiple-term exponents. If I'm wrong then the rest of this will not help because I will be solving the first one. \n" ); document.write( "Solving equations where the variable is in an exponent can be done with logarithms. However there is an easier solution if the equation can be rewritten so each side is a power of the same number. Your equation can be solved this way. \n" ); document.write( "The left side is already a power of 10. Can we rewrite the right side so that it is also a power of 10? Or can we rewrite both sides so that they are both powers of the same third number? The answer to the first question is yes: \n" ); document.write( " \n" ); document.write( "The equation now says that two powers of 10 are equal. The only way this can be true is if the exponents are equal. So: \n" ); document.write( "3x+1 = 2 \n" ); document.write( "This is simple to solve: \n" ); document.write( "3x = 1 \n" ); document.write( "x = 1/3 \n" ); document.write( " |
