You can put this solution on YOUR website!
In algebra.com, square root of a number is officially shown as sqrt(x).
\n" ); document.write( "any root of a number greater than that would be shown as root(n,x) where n is the power of the root and x is the number.
\n" ); document.write( "for example:
\n" ); document.write( "square root of 2 would be shown as sqrt(2)
\n" ); document.write( "cube root of 2 would be shown as root(3,2)
\n" ); document.write( "5th root of 2 would be shown as root 5,2)
\n" ); document.write( "etc.
\n" ); document.write( "If you are going to continue to use the V symbol, then enclose the expression that is within the root sign in parentheses.
\n" ); document.write( "Your problem could be restated as:
\n" ); document.write( "V(63xy^3) / V(9x)
\n" ); document.write( "Algebra.com notation would show it as:
\n" ); document.write( "sqrt(63xy^3) / sqrt(9x)
\n" ); document.write( "If you put 3 curly brackets in front and 3 curly brackets in back, then the algebra.com formula generator would show it as:
\n" ); document.write( "\"sqrt%2863xy%5E3%29+%2F+sqrt%289x%29\"
\n" ); document.write( "The front curly brackets look like {.
\n" ); document.write( "The back curly brackets look like }.
\n" ); document.write( "On your keyboard, they would be to the right of the P.
\n" ); document.write( "They would be Shift [ and Shift ] (upper case letters on those keys).
\n" ); document.write( "That's on my keyboard which is a Toshiba. Your keyboard might be different but possibly not.
\n" ); document.write( "Anyway, back to your problem.
\n" ); document.write( "you have sqrt(63xy^3) / sqrt(9x).
\n" ); document.write( "This is equivalent to sqrt(63xy^3/9x).
\n" ); document.write( "The x in the numerator and the x in the denominator cancel out and you are left with sqrt(63y^3/9)
\n" ); document.write( "9 goes into 63 seven times and you are left with sqrt(7y^3)
\n" ); document.write( "y^3 is equivalent to y^2 * y which means you can take the sqrt of y^2 and make it a y outside the square root sign to get y*sqrt(7y).
\n" ); document.write( "That should be your final answer.
\n" ); document.write( "sqrt(63xy^3) / sqrt(9x) is equivalent to y*sqrt(7y).
\n" ); document.write( "In algebra.com formula generator format, that would look like:
\n" ); document.write( "\"sqrt%2863xy%5E3%29+%2F+sqrt%289x%29\" is equivalent to \"y%2Asqrt%287y%29\".
\n" ); document.write( "I have confirmed that the original equation gives you the same answer as the final equation by substituting a value for x and a value for y and solving both the original equation and the final equation.
\n" ); document.write( "Since the answer in both cases came out the same, I am reasonably confident I did it right.\r
