$\"%281%2FR%29+=+%281%2Ff%29+%2B+sqrt%28%281%2Fg%29%5E%284%29%29\"$ get the sqrt((1/g)^(4)) = 1/g^2
\n" ); document.write( " $\"%281%2FR%29+=+%281%2Ff%29+%2B+%281%2F%28g%5E2%29%29\"$ subrtract 1/f both sides
\n" ); document.write( " $\"%281%2FR%29-%281%2Ff%29+=+%281%2F%28g%5E2%29%29\"$ multiply both sides by g^2
\n" ); document.write( " $\"%28g%5E2%29%28%281%2FR%29-%281%2Ff%29%29+=+1\"$ simplify equation by subtracting ((1/R)-(1/f)
\n" ); document.write( " $\"%28g%5E2%29%28%28%28f-R%29%2FRf%29%29+=+1\"$ multiply both sides by Rf/(f-R))\r
\n" ); document.write( "\n" ); document.write( " $\"%28g%5E2%29=+%28Rf%2F%28f-R%29%29%29\"$ get the square root of both side \r
\n" ); document.write( "\n" ); document.write( "Final Answer:
