You can put this solution on YOUR website!
your equation is:
\n" ); document.write( " $\"%287.1%2A10%5E%28-7%29%29%2A%288.6%2A10%5E%28-5%29%29\"$
\n" ); document.write( "this is equivalent to:
\n" ); document.write( " $\"%287.1%29%2A%288.6%29%2A%2810%5E%28-7%29%29%2A%2810%5E%28-5%29%29\"$
\n" ); document.write( "since $\"%28b%5Ea%29%2A%28b%2Ac%29+=+b%5E%28a%2Bc%29\"$ , this becomes:
\n" ); document.write( " $\"61.06+%2A+10%5E%28%28-7%29%2B%28-5%29%29\"$ which becomes:
\n" ); document.write( " $\"61.06+%2A+10%5E%28-12%29\"$
\n" ); document.write( "this is equivalent to:
\n" ); document.write( " $\"6.106+%2A+10%5E%28-11%29\"$ in strict scientific notation where you have 1 digit to the left of the decimal point and the rest of the digits to the right of it.
\n" ); document.write( "since $\"6.106+%2A+10%5E1\"$ is equivalent to 61.06, then your expression became:
\n" ); document.write( " $\"6.106+%2A+10%5E1+%2A+10%5E%28-12%29\"$
\n" ); document.write( "since $\"b%5Ea+%2A+b%5Eb+=+b%5E%28a%2Bb%29\"$ , this became:
\n" ); document.write( " $\"6.106+%2A+10%5E%281+%2B+%28-12%29%29\"$ which equals:
\n" ); document.write( " $\"6.106+%2A+10%5E%28-11%29\"$ \r
