Question

Ill give 20 points for who ever can help me with these 2 simple questions! Thank you again!

Answer 1

11. remember
$(ab)^c=(a^c)(b^c)$
and
$(x^m)^n=x^{mn}$
so
$\pi (6x^9y^5)^2= \pi (6^2)((x^9)^2)((y^5)^2)=\pi(36)(x^{18})(y^{10})$
B is right

12. $(x^m)(x^n)=x^{m+n}$

so
$(x^1)(x^2y)(y^2)=(x^1)(x^2)(y^1)(y^2)=x^3y^3$
C is answer
