I'm not understanding so the answer should read as follows and steps:
15x^4y^9 divided by 3x^2y^2 = 5x^2y^7
Can you check this one for me.
Direction. Simplify each of the following expressions where possible.
6x^2y^3+9x^2y^3 divided by 3x^2y^2
My answer:
15x^4y^6 divided by 3x^2y^2 =5x^2y^4
There is a + sign in the numerator. You may not add x^{2} to x^{2} and get x^{4}. Multiply, yes, not add. Likewise, y^{3</suo>times y3 is y6 but the sum is not that.
My answer was garbled because I didn't use the superscripts right.
use liner combinations to solve the liner system
v  w = 5
v + 2w = 4
