Answer:

−x^2−11

Step-by-step explanation:

Distribute the Negative Sign:

=−3x−4+−1(x^2−3x+7)

=−3x+−4+−1x^2+−1(−3x)+(−1)(7)

=−3x+−4+−x^2+3x+−7

Combine Like Terms:

=−3x+−4+−x^2+3x+−7

=(−x^2)+(−3x+3x)+(−4+−7)

=−x^2+−11

Which expression is equivalent to 36^-1/2

inn [45]

ANSWER

$( {36})^{ (- \frac{1}{2}) } = \frac{1}{6}$

EXPLANATION

The given expression is

${36}^{( - \frac{1}{2} )}$
This is having a negative index. We must first of all change to a positive index.

Recall that,

${a}^{ - m} = \frac{1}{ {a}^{m} }$

We apply this law of exponents to get,

${36}^{( - \frac{1}{2} )} = \frac{1}{ {36}^{( \frac{1}{2} )} }$

We cab rewrite the given expression to obtain;

${36}^{( - \frac{1}{2} )} = \frac{1}{ \sqrt{36} }$

This will simplify to give us,

${36}^{( - \frac{1}{2} )} = \frac{1}{ 6 }$
