A:

begin mathsize 14px style Suppose space we space want space to space find space cube space root space of space 64.
Then comma space by space prime space factorisation comma space we space have
64 equals 2 cross times 2 cross times 2 cross times 2 cross times 2 cross times 2
We space will space group space them space in space triplet.
straight i. straight e. space 64 equals bottom enclose 2 cross times 2 cross times 2 end enclose cross times bottom enclose 2 cross times 2 cross times 2 end enclose
