Algebra.Com's Answer #295019 by jsmallt9(3758)![]() ![]() ![]() You can put this solution on YOUR website! These problems are easy if you understand what logarithms are and have a basic understanding of exponents. \n" ); document.write( "Logarithms are exponents. The expression: \n" ); document.write( " \n" ); document.write( "represents the exponent for a that results in b. In other words, it represents the power of a that results in b. \n" ); document.write( "So \n" ); document.write( " \n" ); document.write( "represents the power of 8 that results in 1/8. So what power of 8 is 1/8? Answer: -1. (If this is not clear to you, then review what an exponent of -1 means.) So \n" ); document.write( " \n" ); document.write( "Your second expression \n" ); document.write( " \n" ); document.write( "is even easier. What power of 8 is 8? Answer: 1! So \n" ); document.write( " |
