2) Simplify the expression:

[tex]\[ \frac{2a}{\sqrt{2ax}} \][/tex]


Sagot :

Alright, let's simplify the expression [tex]\(\frac{2 a}{\sqrt{2 a x}}\)[/tex] step by step.

1. Start with the original expression:
[tex]\[ \frac{2 a}{\sqrt{2 a x}} \][/tex]

2. Observe that the terms inside the square root can be separated into their individual square roots:
[tex]\[ \sqrt{2 a x} = \sqrt{2} \cdot \sqrt{a} \cdot \sqrt{x} \][/tex]

Thus, the expression becomes:
[tex]\[ \frac{2 a}{\sqrt{2} \cdot \sqrt{a} \cdot \sqrt{x}} \][/tex]

3. Separate the terms in the numerator and the denominator:
[tex]\[ \frac{2 a}{\sqrt{2} \cdot \sqrt{a} \cdot \sqrt{x}} = \frac{2 a}{\sqrt{2} \sqrt{a} \sqrt{x}} = \frac{2 a}{\sqrt{2} \cdot \sqrt{a} \cdot \sqrt{x}} \][/tex]

4. Simplify the fraction by dividing [tex]\(2a\)[/tex] by [tex]\(\sqrt{a}\)[/tex]:
[tex]\[ \frac{2 a}{\sqrt{2} \cdot \sqrt{a} \cdot \sqrt{x}} = \frac{2 \cdot a}{\sqrt{a}} \cdot \frac{1}{\sqrt{2} \sqrt{x}} \][/tex]

5. Simplify [tex]\(\frac{a}{\sqrt{a}}\)[/tex]:
[tex]\[ \frac{a}{\sqrt{a}} = \frac{a \cdot a^{-1/2}}{1} = \frac{a^{1}}{a^{1/2}} = a^{1 - 1/2} = a^{1/2} \][/tex]

So, the expression becomes:
[tex]\[ \frac{2 \cdot a^{1/2}}{\sqrt{2} \cdot \sqrt{x}} = \frac{2 \cdot \sqrt{a}}{\sqrt{2} \cdot \sqrt{x}} \][/tex]

6. Simplify [tex]\(\frac{2}{\sqrt{2}}\)[/tex]:
[tex]\[ \frac{2}{\sqrt{2}} = \frac{2}{2^{1/2}} = 2^{1 - 1/2} = 2^{1/2} = \sqrt{2} \][/tex]

7. Combine all the simplified terms:
[tex]\[ \frac{\sqrt{2} \cdot \sqrt{a}}{\sqrt{x}} = \frac{\sqrt{2a}}{\sqrt{x}} \][/tex]

Thus, the simplified expression is:
[tex]\[ \frac{\sqrt{2} \cdot \sqrt{a}}{\sqrt{x}} \][/tex]
