Sagot :

To simplify the given expression [tex]\( x^3 \sqrt[4]{32 x^5 y^3} \)[/tex], we can follow these steps:

1. Understand the original expression:
[tex]\[ x^3 \sqrt[4]{32 x^5 y^3} \][/tex]

2. Rewrite the expression inside the fourth root:
[tex]\[ \sqrt[4]{32 x^5 y^3} \][/tex]

3. Factorize 32:
[tex]\[ 32 = 2^5 \][/tex]
Therefore,
[tex]\[ \sqrt[4]{32 x^5 y^3} = \sqrt[4]{2^5 x^5 y^3} \][/tex]

4. Combine the exponents inside the fourth root:
[tex]\[ \sqrt[4]{2^5 x^5 y^3} = \sqrt[4]{(2x)^5 y^3} \][/tex]

5. Simplify using the property of roots:
[tex]\[ \sqrt[4]{(2x)^5 y^3} = \sqrt[4]{(2x)^5} \cdot \sqrt[4]{y^3} \][/tex]

6. Separate the terms and simplify:
[tex]\[ \sqrt[4]{(2x)^5} = (2x)^{5/4} \][/tex]
And,
[tex]\[ \sqrt[4]{y^3} = y^{3/4} \][/tex]

7. Combine the simplified radical terms:
[tex]\[ x^3 \cdot (2x)^{5/4} \cdot y^{3/4} \][/tex]

8. Rewrite in a single expression:
[tex]\[ x^3 \cdot 2^{5/4} \cdot x^{5/4} \cdot y^{3/4} \][/tex]

9. Combine like terms by adding exponents:
[tex]\[ 2^{5/4} \cdot x^{3+5/4} \cdot y^{3/4} \][/tex]

10. Simplify the exponent:
[tex]\[ x^{3 + \frac{5}{4}} = x^{\frac{12}{4} + \frac{5}{4}} = x^{\frac{17}{4}} \][/tex]

11. Combine everything in the final form:
[tex]\[ 2^{5/4} \cdot x^{17/4} \cdot y^{3/4} \][/tex]

To express as a multiplication with coefficients, convert [tex]\(2^{5/4}\)[/tex] known that [tex]\(2^{5/4} = 2 \cdot 2^{1/4}\)[/tex]:

[tex]\[ 2 \cdot 2^{1/4} \cdot x^{17/4} \cdot y^{3/4} \][/tex]

Therefore, the simplified form of the expression [tex]\(x^3 \sqrt[4]{32 x^5 y^3}\)[/tex] is:

[tex]\[ 2 \cdot 2^{1/4} \cdot x^{17/4} \cdot y^{3/4} \][/tex]
