Answer 1

Answer:

I gues you want a simplification of the number in the image, you have:

$\frac{27C^4D^5}{9C^7D^4}$

To solve this i will use that:

(a^x)/(a^y) = a^(x - y)

first, we separte the division into 3 parts, one with the knowed numbers, other with the variable C and other with the variable D.

$\frac{27C^4D^5}{9C^7D^4} = \frac{27}{9}*\frac{C^4}{C^7}*\frac{D^5}{D^4} = 3C^{4-7} D^{5-4} = 3C^{-3}*D$

this can also be written as:

$\frac{3D}{C^3}$
