odpoveď:
# (1/81) ^ (3/4) = farby (zelená) (1/27) #
vysvetlenie:
od tej doby # 81 = 9xx9 = 3xx3xx3xx3xx3 = 3 ^ 4 #
teda #81^(1/4)=3#
#(1/81)^(3/4)#
#COLOR (biely) ("XXX") = ((1/81) ^ (1/4)) ^ 3 #
#COLOR (biely) ("XXX") = ((1 ^ (1/4)) / (81 ^ (1/4))) ^ 3 #
#COLOR (biely) ("XXX") = (1/3) ^ 3 #
#COLOR (biely) ("XXX") = 1 / (3 ^ 3) #
#COLOR (biely) ("XXX") = 1/27 #
