Answer:

$6^{-3} = \frac{1}{6^3} =\frac{1}{6*6*6}=\frac{1}{216}$

The expression $6^{-3}$ can be simplified using rules for negative exponents - move the base to the denominator. After following this rule, simplify.

$6^{-3} = \frac{1}{6^3} =\frac{1}{6*6*6}=\frac{1}{216}$

Answer:

$f(a) = \frac{(a+5)}{(a-1)}$

Step-by-step explanation:

Given : $f(x) = \frac{(3+x)}{(x-3)}$

In order to find $f(a+2)$ we will substitute $(a+2)$ for $x$ in the given function, that is :

$f(a) = \frac{(3+a+2)}{(a+2-3)}$

$f(a) = \frac{(a+5)}{(a-1)}$
