Sagot :

To simplify the expression [tex]\(\left(x y z^2\right)^4\)[/tex], we need to apply the property of exponents that states [tex]\((a \cdot b \cdot c)^n = a^n \cdot b^n \cdot c^n\)[/tex].

Step-by-Step Solution:

1. Identify the individual terms inside the parentheses:
The given expression is [tex]\(\left(x y z^2\right)^4\)[/tex]. Here, [tex]\(a = x\)[/tex], [tex]\(b = y\)[/tex], and [tex]\(c = z^2\)[/tex].

2. Apply the exponent to each term within the parentheses:
We raise each term inside the parentheses to the power of 4:
[tex]\[ \left(x y z^2\right)^4 = x^4 \cdot y^4 \cdot (z^2)^4 \][/tex]

3. Simplify the [tex]\(z\)[/tex] term:
For the term [tex]\((z^2)^4\)[/tex], we use the property of exponents [tex]\((z^m)^n = z^{m \cdot n}\)[/tex]:
[tex]\[ (z^2)^4 = z^{2 \cdot 4} = z^8 \][/tex]

4. Combine the results:
Now we combine all the simplified terms:
[tex]\[ x^4 \cdot y^4 \cdot z^8 \][/tex]

This means the simplified form of the expression [tex]\(\left(x y z^2\right)^4\)[/tex] is [tex]\(x^4 y^4 z^8\)[/tex].

Final Answer:
[tex]\[ \boxed{x^4 y^4 z^8} \][/tex]
