Posted by on .

I am really having problems with monomials: Please help!
Simplify:

4x^2 y^3 Z
----------- (divided by)
5y^4 Z^3

is the answer
4x
------ (divided by)
5yz^2

  • Algebra - ,

    With monomials, you can look at each unknown (variable) individually when you do a division:
    4x²
    ------- = 4x²/5
    5

    y³/y4 = 1/y

    z/z³ = 1/z²

    So putting everything together:
    4x^2 y^3 Z / 5y^4 Z^3
    4x²/(5yz²)

    Explain the difference in answers between the following exponential expressions. Include the solutions?

    7^2, -7^2,(-7)^2, and 7^-2
