    (9-7) ^3 (5^0) + (8+3) ^2

    = (2^3) (5^0) + (8+3) ^ 2

    = 8 (5^0) + (8+3) ^ 2

    = (8) (1) + (8+3) ^ 2

    = 8 + (8+3) ^ 2

    = 8 + 11^2

    = 8+121

    = 129

    3.2 (10^5) + 1.25 (10 ^4) + 2.9 (10^5)

    = (3.2) (100000) + 1.25 (104) + 2.9 (105)

    = 320000 + 1.25 (10 ^4) + 2.9 (10^5)

    = 320000 + (1.25) (10000) + 2.9 (10 ^5)

    = 320000+12500 + 2.9 (10 ^5)

    = 332500 + 2.9 (10 ^5)

    = 332500 + (2.9) (100000)

    = 332500+290000

    =622500
