Question

Now recall that for an odd positive number n, the principal nth root of a real number a is the real number b such that n a = b if and only if a = bn. Therefore, we should factor the radicand a = x3y −8 into factors that are products of perfect cubes and other factors. Notice that −8 =

          Now recall that for an odd positive number n, the principal nth root of a real number a is the real number b such that 
n
a
 = b
 if and only if 
a = bn.
Therefore, we should factor the radicand 
a = 
x3y
−8
 into factors that are products of perfect cubes and other factors.
Notice that 
−8 =
