Which expression represents the area of a rectangle with
sides measuring 7x4y2z units and
2xy5z14?

______________________________

Note:

 - It doesn't matter which measurement fills the height or width part in the formula.

Equation at the end of Step 1:

Note:

 - To multiply powers of the same base, you can add their exponents. So you just do .

 - When you have a plain variable like , you can assume .

Equation at the end of Step 2:

Note:

 - To multiply powers of the same base, you can add their exponents. So you just do .

Equation at the end of Step 3:

Note:

 - To multiply powers of the same base, you can add their exponents. So you just do .

 - When you have a plain variable like , you can assume .

Equation at the end of Step 4:

Note:

- Since we combine all the powers and multiplied the bases, all you have to do is put it all together in 1 form like we were doing after we added powers in the earlier steps.

Equation at the end of All Steps:
