Simplify the following expression:

[tex]\[ \sqrt[3]{4} \cdot 4^{\frac{1}{3}} + \sqrt[5]{4} \cdot 4^{\frac{3}{5}} \][/tex]


Sagot :

To solve the expression [tex]\(\sqrt[3]{4} \cdot 4^{\frac{1}{3}} + \sqrt[5]{4} \cdot 4^{\frac{3}{5}}\)[/tex], we can follow these detailed steps:

Step 1: Simplify each term separately

1. First Term: [tex]\(\sqrt[3]{4} \cdot 4^{\frac{1}{3}}\)[/tex]

We know that [tex]\(\sqrt[3]{4}\)[/tex] can be written as [tex]\(4^{\frac{1}{3}}\)[/tex]. So the first term is:
[tex]\[ \sqrt[3]{4} \cdot 4^{\frac{1}{3}} = 4^{\frac{1}{3}} \cdot 4^{\frac{1}{3}} \][/tex]

Using the properties of exponents, particularly that [tex]\(a^m \cdot a^n = a^{m+n}\)[/tex]:
[tex]\[ 4^{\frac{1}{3}} \cdot 4^{\frac{1}{3}} = 4^{\frac{1}{3} + \frac{1}{3}} = 4^{\frac{2}{3}} \][/tex]

Numerically, [tex]\(4^{\frac{2}{3}}\)[/tex] is approximately:
[tex]\[ 4^{\frac{2}{3}} \approx 2.519842099789746 \][/tex]

2. Second Term: [tex]\(\sqrt[5]{4} \cdot 4^{\frac{3}{5}}\)[/tex]

Similarly, [tex]\(\sqrt[5]{4}\)[/tex] can be written as [tex]\(4^{\frac{1}{5}}\)[/tex]. Hence, the second term is:
[tex]\[ \sqrt[5]{4} \cdot 4^{\frac{3}{5}} = 4^{\frac{1}{5}} \cdot 4^{\frac{3}{5}} \][/tex]

Using the properties of exponents:
[tex]\[ 4^{\frac{1}{5}} \cdot 4^{\frac{3}{5}} = 4^{\frac{1}{5} + \frac{3}{5}} = 4^{\frac{4}{5}} \][/tex]

Numerically, [tex]\(4^{\frac{4}{5}}\)[/tex] is approximately:
[tex]\[ 4^{\frac{4}{5}} \approx 3.0314331330207955 \][/tex]

Step 2: Add the two simplified terms together

Now that we have the approximate values for each term, we can add them together:
[tex]\[ 4^{\frac{2}{3}} + 4^{\frac{4}{5}} \approx 2.519842099789746 + 3.0314331330207955 \][/tex]

The sum of these values is approximately:
[tex]\[ 2.519842099789746 + 3.0314331330207955 \approx 5.551275232810541 \][/tex]

So, the result of the expression [tex]\(\sqrt[3]{4} \cdot 4^{\frac{1}{3}} + \sqrt[5]{4} \cdot 4^{\frac{3}{5}}\)[/tex] is approximately [tex]\(5.551275232810541\)[/tex].
