  1. 1)
    a) 2 . 2 . 2 . 2 . 2 = 2^5
    b) 3 . 3 . 3 = 3^3
    c) 6 . 6 . 6 . 3 . 2 = 6 . 6 . 6 . ( 3.2) = 6 . 6 . 6 . 6 = 6^4
    d) 100 . 10 . 10 . 10 = 10 . 10 . 10 . 10 . 10 = 10^5

  2. a,
    2.2.2.2.2
    = 2^1 . 2^1 . 2^1 . 2^1 . 2^1
    = 2^(1 + 1 + 1 + 1 + 1)
    = 2^5
    b,
    3.3.3
    = 3^1 . 3^1 . 3^1
    = 3^(1 + 1 + 1)
    = 3^3
    c,
    6.6.6.3.2
    = 6^1 . 6^1 . 6^1 . 6^1
    = 6^(1 + 1 + 1 + 1)
    = 6^4
    d,
    100 . 10 . 10 . 10
    = 10 . 10 . 10 . 10 . 20
    = 10^1 . 10^1 . 10^1 . 10^1 . 10^1
    = 10^(1 + 1 + 1 + 1 + 1)
    = 10^5
