Question

Easton simplified the following expression:

(x2y6z5)(x4y5z3)

If he writes his answer in the form of xaybzc, what is the value of b, the exponent on y?

Answer 1

just add the exponents of y you already have
remember this
\[ a^na^m=a^{n+m} \]

Answer 2

\[\Large (x^{2}y^{6}z^{5})(x^{4}y^{5}z^{3}) = (x^{2}x^{4})(y^{6}y^{5})(z^{5}z^{3})\]

Use the wquation @helder_edwin posted.

Answer 3

\[a^m a^n=a^{m+n}\] Figure it out.

Answer 4

.... x^2y^5z^3(yz^2+x^2) ?

Answer 5

No idea how you got that. You add the EXPONENTS, not the variables.

Answer 6

Example:
\[\LARGE T^{4}T^{7} = T^{4+7} = T^{11}\]

Answer 7

okay i get it now .

Answer 8

so the answer is?......
