Write in simplified radical form with at most one radical. Assume that the variable represents a positive real number.

[tex]\[ \sqrt[3]{v} \cdot \sqrt[5]{v^2} \][/tex]


Sagot :

To simplify the expression [tex]\(\sqrt[3]{v} \cdot \sqrt[5]{v^2}\)[/tex], we proceed as follows:

1. Convert the radicals to exponents:
[tex]\(\sqrt[3]{v}\)[/tex] can be written as [tex]\(v^{1/3}\)[/tex].
[tex]\(\sqrt[5]{v^2}\)[/tex] can be written as [tex]\(v^{2/5}\)[/tex].

2. Multiply the exponents:
When multiplying expressions with the same base, we add the exponents:
[tex]\[ v^{1/3} \cdot v^{2/5} = v^{1/3 + 2/5} \][/tex]

3. Find a common denominator and add the exponents:
The common denominator for 3 and 5 is 15.
[tex]\[ \frac{1}{3} = \frac{5}{15} \][/tex]
[tex]\[ \frac{2}{5} = \frac{6}{15} \][/tex]
Adding these fractions gives:
[tex]\[ \frac{5}{15} + \frac{6}{15} = \frac{11}{15} \][/tex]

4. Express the product in exponential form:
[tex]\[ v^{1/3 + 2/5} = v^{11/15} \][/tex]

Therefore, [tex]\(\sqrt[3]{v} \cdot \sqrt[5]{v^2}\)[/tex] simplifies to [tex]\(v^{11/15}\)[/tex].

The simplified form in terms of a radical with at most one radical is:

[tex]\[ v^{11/15} \text{ (as an exponent, this is already in its simplest form, and there is no need to revert back to a radical form as it would complicate the expression unnecessarily)} \][/tex]
