Simplify
11x9y(3y7)

Answer 1

Is it?
\[11x^9y(3y^7)\]

Answer 2

yes

Answer 3

If you look at that it's actually
\[11 \times x^9 \times y \times 3 \times y^7\]
So these can be multiplied together
\[\color{red}{11} \times x^9 \times \color{blue}{y} \times \color{red}{3} \times \color{blue}{y^7}\]

Answer 4

33x9y8 ?

Answer 5

\[11 \times 3=33 \\ y \times y^7=y^{1+7}=y^8\]
--------------------------------------------
Then you get
\[33x^9y^8\]

Answer 6

Yep
