Algebra.Com's Answer #152250 by RAY100(1637)![]() ![]() ![]() You can put this solution on YOUR website! Try this, assume that the digits are the same, \n" ); document.write( ". \n" ); document.write( "xx,xxx,,,,,or x+x+x+x+x (Sum of Digits) \n" ); document.write( ". \n" ); document.write( "if y = factor,,,,use 5 factors(somewhat arbitrary),again all factors same \n" ); document.write( ", \n" ); document.write( "As a 1st est,,,5th root of 10000 = 6.3,, therefore use 7 \n" ); document.write( ", \n" ); document.write( "7^5 = 16,807,,,1+6+8+0+7 = 22 vs 5*7 =35 \n" ); document.write( ", \n" ); document.write( "trying 8, 8^5 = 32768,,,,3+2+7+6+8=26, vs 5*8=40 \n" ); document.write( ". \n" ); document.write( "from this pattern we see that the power should increase, and the base degrease \n" ); document.write( ", \n" ); document.write( "following this pattern, bring us to 3^9= 19683 \n" ); document.write( "Sum of Digits = 1+9+6+8+3 = 27,,,and 9*3 =27 \n" ); document.write( ". \n" ); document.write( "Might be a number closer to 10,000, but this works \n" ); document.write( " |
