I am having trouble working out the expression (25(x^4)(y^6))^(1/2) \n" ); document.write( "the book says the answer is 5x^2|y|^3 \n" ); document.write( "----- \n" ); document.write( "The book is correct. \n" ); document.write( "Since the exponent is on the outer parentheses, \n" ); document.write( "take the square root of each factor \n" ); document.write( "sqrt(25) = 5 \n" ); document.write( "sqrt(x^4) = x^2 \n" ); document.write( "sqrt(y^6) = y^3 \n" ); document.write( "------- \n" ); document.write( "So the answer is 5*x^2*y^3 \n" ); document.write( "------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "----------------- \n" ); document.write( " |
