+128475 1. Notice, NSS, that
4/7 * 4/7 * 4/7 * 4/7 = 256 / 2401
But also
-4/7 * -4/7 * -4/7 * -4/7 = 256 / 2407
So..... (4/7, -4/7) is correct
2. √[ 36 g^6] =
Write this as an exponential...it makes it easier to see, IMHO.....so we have
(36)^(1/2) * (g^6)^(1/2) =
(6^2)^(1/2) * ( g^3) =
[ use (a^m)^n = a^(m * n) ]
6 * g^3
