    expressing decimals; evaluating expressions; simplifying

    1) Write each decimal using negative exponents:

    . . .a) 0.1
    . . .b) 0.01
    . . .c) 0.0001
    . . .d) 0.00001

    2) Evaluate each expression if w = -2, x = 3, and y = -1:

    . . .a) x - 4
    . . .b) w - 7
    . . .c) 8w
    . . .d) (xy) - 6

    3) Use Product of Power and Quotient of Power rules to simplify each expression:

    . . .a) x - 2 x x - 3
    . . .b) r - 5 x r 9

    Your post was almost impossible to decipher; if I have misunderstood your meaning (above), please reply with correction.

    When you reply, please show all of your work and reasoning so far. For instance, the decimals are pretty simple: just convert, using what you've learned about scientific notation. The evaluation is pretty simple: plug the values in for the letters, and simplify. The simplification might be a little difficult, but we can't find where you're having trouble until we can see what you've tried.

    Please be specific. Thank you.

    Eliz.
