x^-.3=.3714 ...we can write this as
1/(x3/10) = 3714/10000 .... and when two fractions are equal, their reciprocals are equal, too...so we have...
(x3/10) = 10000/3714 ......exponentiate both sides to the (10/3) power
x = (10000/3714)(10/3) = about 27.156 (we could have also solved this problem using logs, too)
