Question

Find the product.

3y^2 z(2y^2 z + 4yz - y + z)

=6y^(4z) + 12y^(1+2z)z - 3y^(1+2z) + 3zy^(2z)?

Answer 1

\[3y^2z(2y^2z+4yz-y+z)\]
Is this your question?

Answer 2

yes

Answer 3

You have your grouping wrong in your answer which may not be the answer you have written on paper.

Answer 4

Multiply the whole bracket with 3y^2z

3y^2 z(2y^2 z + 4yz - y + z)
6y^4z^2+12y^3z^2-3y^3z+3y^2z^2

Answer 5

Reads like this:
\[6y^{4z} + 12y^{1+2z}z - 3y^{1+2z} + 3zy^{2z}\]

Answer 6

o h i see what i did thank you

Answer 7

Uri's answer is correct. And looks like this:
\[3y^2 z(2y^2 z + 4yz - y + z)\]
\[6y^4z^2+12y^3z^2-3y^3z+3y^2z^2\]
