Let's take it one part at a time. YOu were given the following equation:
\n" ); document.write( "\"sqrt%28x+%2B+3%29+=+81\"
\n" ); document.write( "---
\n" ); document.write( "1)What is the value of x+3?
\n" ); document.write( "We square both sides to get
\n" ); document.write( "x + 3 = 81^2
\n" ); document.write( "or
\n" ); document.write( "x + 3 = 6561
\n" ); document.write( "---
\n" ); document.write( "2)What is the value of x?
\n" ); document.write( "subtract 3 from both sides to get
\n" ); document.write( "x = 6558
\n" ); document.write( "---
\n" ); document.write( "3)What is the value of 3*sqrt x+3?
\n" ); document.write( "we already know, sqrt(x+3) = 81, so,
\n" ); document.write( "3*sqrt(x+3) = 3*81 = 243.
\n" ); document.write( "
\n" );
