You can put this solution on YOUR website!
your equation is 8 = b^-2.
\n" ); document.write( "since b^-2 = 1/b^2, this equation becomes 8 = 1/b^2.
\n" ); document.write( "multiply both sides of this equation by b^2 and divide both sides of this equation by 8 to get b^2 = 1/8.
\n" ); document.write( "take the square root of both sides of this equation to get b = plus or minus sqrt(1/8).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "to confirm this solution is correct, replace b with plus or minus sqrt(1/8) and solve the equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "put in your calculator (sqrt(1/8)^-2 and the calculator will tell you that the answer is 8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "put in your calculator (-sqrt(1/8)^-2 and the calculator will tell you that the answer is 8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this confirms the solution is correct.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the solution is b = plus or minus sqrt(1/8).\r
