Question

Easton simplified the following expression:

(x^2y^6z^5)(x^4y^5z^3)

If he writes his answer in the form of x^a y^b z^c, what is the value of b, the exponent on y?

Answer 1

\[x^6 y^11 z^8\]

Answer 2

(x^2y^6z^5)(x^4y^5z^3) = x^6y^11z^8

so b = 11

Answer 3

(x^2 y^6 z^5) (x^4 y^5 z^3)
-> y^6 * y^5 = y^11
Thus b = 11
