Use the quotient of powers property to simplify

[tex]\[ \frac{2^{\frac{2}{5}}}{2^{\frac{1}{10}}} = \][/tex]

[tex]\[ \qquad \][/tex]


Sagot :

Sure, let's simplify the given expression using the quotient of powers property. The expression we need to simplify is:

[tex]\[ \frac{2^{\frac{2}{5}}}{2^{\frac{1}{10}}} \][/tex]

### Step-by-Step Solution

1. Identify the exponents:

The numerator has an exponent of [tex]\(\frac{2}{5}\)[/tex].
The denominator has an exponent of [tex]\(\frac{1}{10}\)[/tex].

2. Apply the quotient of powers property:

The quotient of powers property states that [tex]\(\frac{a^m}{a^n} = a^{m-n}\)[/tex]. Therefore, we subtract the exponent in the denominator from the exponent in the numerator.

[tex]\[ \frac{2^{\frac{2}{5}}}{2^{\frac{1}{10}}} = 2^{\frac{2}{5} - \frac{1}{10}} \][/tex]

3. Common denominator for exponents:

To subtract the exponents, we need a common denominator. The denominators are 5 and 10. The least common denominator is 10.

[tex]\[ \frac{2}{5} = \frac{2 \times 2}{5 \times 2} = \frac{4}{10} \][/tex]

Now we have:

[tex]\[ 2^{\frac{4}{10} - \frac{1}{10}} \][/tex]

4. Subtract the exponents:

Subtracting the exponents with a common denominator:

[tex]\[ \frac{4}{10} - \frac{1}{10} = \frac{4 - 1}{10} = \frac{3}{10} \][/tex]

Thus, we get:

[tex]\[ 2^{\frac{3}{10}} \][/tex]

5. Simplify the expression:

So, the simplified form of the original expression is:

[tex]\[ 2^{\frac{3}{10}} \][/tex]

### Calculation of the Result

For completeness, let's also express the actual value:

[tex]\[ 2^{\frac{3}{10}} \approx 1.2311444133449163 \][/tex]

So, [tex]\(\frac{2^{\frac{2}{5}}}{2^{\frac{1}{10}}} = 2^{\frac{3}{10}}\approx 1.2311444133449163 \)[/tex].

But for the exact answer in the simplified form:

[tex]\[ \boxed{2^{\frac{3}{10}}} \][/tex]
