1 answer:

7 0

$r = \frac{18}{6} \\ 
r = 3 \\ 
 \\ 
 a_{n} = a_{1} * r^{n-1} \\ 
 a_{8} = 6 * 3^{8 - 1} \\ 
a_{8} = 6 * 3^{7} \\
a_{8} = 6 * 2187 \\
a_{8} = 13122

Simplify. (x6 y3)(−8xy2)(−6x3)

When simplifying this, we would have to take this little by little in serious steps and not only this, but to also take notice of the use of pemdas and to make sure that we take each step carefully.

We first would (first) simplify the following:

$(((x^6)*(y^3))*(0-(8x*(y^2))))*(0-(2*3x^3)) \\ \\ then \ we \ would \ do . . . . \\ \\ x^7 \ multiplied \ by \ x^3 \ = x^(^7^ +^ 3^) = \ x^1^0 \\ \\ (last \ step).... \\ \\ 2^3 \ multiplied \ by \ 2^1 = 2^(^3^ +^ 1^) = 2^4 \\ \\ \Longrightarrow \ (your \ answer) \\ \\ \boxed{\bf{ (2^4*3x^1^0y^5)}}$
