Explanation:

#(7^(2/9))/(6 3/4)#

#:.2/9=0.222222222#

#:.6 3/4=6.75#

On the calculator press# 7# then# x^y# then#0.222222222=1.540989091#

#:.7^(2/9)=1.540989091#

#:.6 3/4=6.75#

#:.1.540989092/6.75#

#:.0.22829468#

#:.0.228# to the nearest 3 decimal places

or:-

#:.7^(2/9)=root9(7^2)#

#:.=(root9(7^2))/(6 3/4)#
