Question

(3x2y6)7

Answer 1

2187x14y42

Answer 2

they just want you to distribute the 7?

Answer 3

Oh I just simplified it.

Answer 4

they actually want you to use the power of a power law for indexes

\[(x^a)^b = x^{a \times b}\]

and the index or power of 7 operates on each part

\[(3)^7 \times (x^2)^7 \times (y^6)^7\]

Answer 5

I see. nice!

Answer 6

(x + y + 3)(x + y - 4) multiplying polynomials

Answer 7

well its simply

\[x(x + y -4) +y(x + y -4) +3(x + y -4) \]

distribute and then collect like terms to simplify
