3. Simplify the expression.

[tex]\[

\][/tex]

A. [tex]\(-\frac{3 m^4}{m^{-2}}\)[/tex]

B. [tex]\(-m^{216}\)[/tex]

C. [tex]\(m^{18}\)[/tex]

D. [tex]\(\frac{1}{m^{18}}\)[/tex]



Answer :

Sure, let's simplify the given expression step by step.

### Step 1: Simplify the first expression:
[tex]\[ \left(\frac{m^{-1} m^5}{m^{-2}}\right)^{-3} \][/tex]

First, simplify the expression inside the parentheses:

Combine the powers of [tex]\(m\)[/tex] inside the fraction:
[tex]\[ m^{-1} \cdot m^5 = m^{-1 + 5} = m^4 \][/tex]

Now we have:
[tex]\[ \left(\frac{m^4}{m^{-2}}\right)^{-3} \][/tex]

Next, simplify the fraction:
[tex]\[ \frac{m^4}{m^{-2}} = m^{4 - (-2)} = m^{4 + 2} = m^6 \][/tex]

Now, we raise this to the power of [tex]\(-3\)[/tex]:
[tex]\[ (m^6)^{-3} = m^{6 \cdot (-3)} = m^{-18} \][/tex]

So, the simplified form of the first expression is:
[tex]\[ m^{-18} \][/tex]

### Step 2: Simplify the second expression:
[tex]\[ -\frac{3 m^4}{m^{-2}} \][/tex]

Simplify the fraction by combining the powers of [tex]\(m\)[/tex]:
[tex]\[ -\frac{3 m^4}{m^{-2}} = -3 \cdot m^{4 - (-2)} = -3 \cdot m^{4 + 2} = -3 \cdot m^6 \][/tex]

So, the simplified form of the second expression is:
[tex]\[ -3m^6 \][/tex]

### Final Answer:
Thus, after simplifying the given expressions, we get:
1. [tex]\(\left(\frac{m^{-1} m^5}{m^{-2}}\right)^{-3}\)[/tex] simplifies to [tex]\(\boxed{m^{-18}}\)[/tex]
2. [tex]\(-\frac{3 m^4}{m^{-2}}\)[/tex] simplifies to [tex]\(\boxed{-3m^6}\)[/tex]
