b³-2a³/b³+2a³
=(5)³-2(3)³/(5)³+2(3)³
=125-2*9/125+2*9
=125-18/125+18
=107/143
=0.748
=(5)³-2(3)³/(5)³+2(3)³
=125-2*9/125+2*9
=125-18/125+18

Really sorry I made a mistake
Wait for 2 minutes I will give you correct ans
Your book's ans is correct
First line: (5)³-2*(3)³/(5)³+2*(3)³
=125-2*27/125+2*27
=125-54/125+54
=71/179 or 71:179
