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
