b) [tex]\sqrt{\sqrt[3]{x^{10} \cdot x^2}} =[/tex]

Sagot :

To solve the expression [tex]\(\sqrt{\sqrt[3]{x^{10} \cdot x^2}}\)[/tex], we need to simplify step by step, applying the rules of exponents and roots.

1. Combine the Exponents Inside the Cubic Root:
Start with the inside of the cubic root: [tex]\(x^{10} \cdot x^2\)[/tex]:

[tex]\[ x^{10} \cdot x^2 = x^{10 + 2} = x^{12} \][/tex]

2. Apply the Cubic Root:
Next, take the cubic root of [tex]\(x^{12}\)[/tex]:

[tex]\[ \sqrt[3]{x^{12}} = (x^{12})^{1/3} \][/tex]

By the rules of exponents, [tex]\((a^m)^n = a^{m \cdot n}\)[/tex]:

[tex]\[ (x^{12})^{1/3} = x^{12 \cdot \frac{1}{3}} = x^{4} \][/tex]

3. Apply the Square Root:
Finally, take the square root of the result:

[tex]\[ \sqrt{x^4} = (x^4)^{1/2} \][/tex]

Using the exponent rule again:

[tex]\[ (x^4)^{1/2} = x^{4 \cdot \frac{1}{2}} = x^{2} \][/tex]

4. Conclusion:
Therefore, the simplified expression is:

[tex]\[ \sqrt{\sqrt[3]{x^{10} \cdot x^2}} = x^{2} \][/tex]
