Evaluate each expression for the given value(s) of the variables(s).

masya89 [10]

Answer:

9. $\frac{1}{10,000} = 0.0001$

10. $\frac{1}{81}$

Step-by-step explanation:

9. $x^{-4}$

Evaluate when x = 10.

Substitute x = 10 into the expression

$10^{-4}$

Apply the negative exponent rule ( $a^{-n} = \frac{1}{a^n}$ )

Thus:

$= \frac{1}{10^4}$

$= \frac{1}{10^4} = \frac{1}{10,000} = 0.0001$

10. $2a^{-1}b^{-3}$

Evaluate when a = 6 and b = 3

Substitute

$(2*6^{-1})(3^{-3})$

Apply the negative exponent rule

$(2*\frac{1}{6})(\frac{1}{3^3})$

$(\frac{2}{6})(\frac{1}{27})$

$\frac{2*1}{6*27}$

$\frac{1}{81}$
