    1.

    3 * 10^4 * 7 * 10^-4

    7*3 = 21

    10^4 * 10^-4 = 10^0 = 1

    21 * 1 = 21

    2.1 * 10^1

    2. (5*10^4)^2=

    25 * 10^8 = 2.5 * 10^9

    it needs to be written in scientific notation.

    woops for the first I looked at it wrong...

    3 * 10^10 xs 7 x 10^-4

    = 21 x 10^6

    = 2.1 x 10^7

    And ma'm, I believe it is written in scientific notation...
