Algebra.Com's Answer #20139 by Nate(3500)![]() ![]() ![]() You can put this solution on YOUR website! a)Using a calculator, find log 10000 where log means log to the base of 10. \n" ); document.write( "actually, you do not need a calculator: \n" ); document.write( "log(base ten) 10,000 = x \n" ); document.write( "10^x = 10,000 \n" ); document.write( "(10)(10)(10)(10) = 10,000 \n" ); document.write( "so.... x is 4 \n" ); document.write( "------------------------------------------- \n" ); document.write( "b)Most calculators have 2 different logs on them: log, which is based 10, and ln, which is based e.
