Simplify:

[tex]\[
\left(-2 w^{-2} x^3\right)^5
\][/tex]

Write your answer using only positive exponents.


Sagot :

Sure, let's simplify the expression [tex]\(\left(-2 w^{-2} x^3\right)^5\)[/tex].

We start by distributing the exponent to each factor inside the parentheses. The expression inside the parentheses is:

[tex]\[ -2 w^{-2} x^3 \][/tex]

We need to raise each part to the 5th power:

[tex]\[ \left(-2\right)^5 \left(w^{-2}\right)^5 \left(x^3\right)^5 \][/tex]

Let's evaluate each part separately.

1. For [tex]\(\left(-2\right)^5\)[/tex]:
[tex]\[ \left(-2\right)^5 = -32 \][/tex]

2. For [tex]\(\left(w^{-2}\right)^5\)[/tex]:
[tex]\[ \left(w^{-2}\right)^5 = w^{-2 \cdot 5} = w^{-10} \][/tex]

3. For [tex]\(\left(x^3\right)^5\)[/tex]:
[tex]\[ \left(x^3\right)^5 = x^{3 \cdot 5} = x^{15} \][/tex]

Now we combine these results:

[tex]\[ \left(-2 w^{-2} x^3\right)^5 = -32 \cdot w^{-10} \cdot x^{15} \][/tex]

To express the result with only positive exponents, we rewrite [tex]\(w^{-10}\)[/tex] as [tex]\(\frac{1}{w^{10}}\)[/tex]:

[tex]\[ -32 \cdot w^{-10} \cdot x^{15} = -32 \cdot \frac{x^{15}}{w^{10}} \][/tex]

So the final simplified expression is:

[tex]\[ \frac{-32 x^{15}}{w^{10}} \][/tex]

Therefore, the simplified form of the given expression is:

[tex]\[ \boxed{\frac{-32 x^{15}}{w^{10}}} \][/tex]
