4th root is the same as to the 1/4 power. We take powers out of logarithms as fraction coefficients.\r
\n" ); document.write( "\n" ); document.write( "So \"In+%5E4sqrt%28ab%5E2%29\"=1/4(ln ab^2)
\n" ); document.write( "Now, multiplied variables/numbers in logarithms can be taken out as addition.
\n" ); document.write( "So (1/4)(ln ab^2)=(1/4)(ln a)+(1/4)(ln b^2)
\n" ); document.write( "Now, repeat the first step for the logarithm with b^2.
\n" ); document.write( "So (1/4)(ln a)+(1/2)(ln b)
\n" ); document.write( "
\n" );
