hi, this is my question:
2X^2 x 3X x 4XY=?
would the answer be 48XY?
if not could you please explain where i am going wrong!
Thanks
No.
$\displaystyle 2x^{2} \times 3x \times 4xy$
You multiply the numbers "separate" from the variables. You got that 2 x 3 x 4 = 24. What Ackbeet was getting at were the variables.
Note that you have to multiply $\displaystyle x^{2} \cdot x \cdot x$ (look at just the x's from the original expression). What is its product? Note that $\displaystyle x = x^1$
