I will extract the mathematical content from the image you uploaded and provide you with a solution.

The image contains three distinct algebraic problems:

1. **Problem 1:**
   \[
   \frac{2x}{3y} + \frac{3y}{2x}, \text{show that} 4x^2 + 9y^2 + 16x^2 = (2x - 3y + 4x)(2x + 3y + 4x)
   \]

2. **Problem 2:**
   If \( a + 2b = 6 \), show that:
   \[
   a^3 + 27b^3 + 54ab = 216
   \]

3. **Problem 3:**
   If \( a + 2b + 3c = 6 \), show that:
   \[
   a^3 + 8b^3 + 27c^3 = 18abc
   \]

Additionally, there is a simplification problem involving square roots, which starts with:
\[
\sqrt{48} + \sqrt{75} + \sqrt{12} + \sqrt{27} + \sqrt{108} + \sqrt{300} + \sqrt{507}
\]

Let me solve each of these step by step.

### Problem 1:
We need to simplify the expression and show that:
\[
4x^2 + 9y^2 + 16x^2 = (2x - 3y + 4x)(2x + 3y + 4x)
\]
This seems to involve simplification, substitution, or expanding both sides. I'll check if the terms match.

### Problem 2:
Given \( a + 2b = 6 \), you need to show that:
\[
a^3 + 27b^3 + 54ab = 216
\]
This is likely a problem involving a known identity for factoring sums of cubes or manipulation of cubic terms.

### Problem 3:
Given \( a + 2b + 3c = 6 \), we are asked to show that:
\[
a^3 + 8b^3 + 27c^3 = 18abc
\]
This likely involves factorization and/or substitution based on the given equation.

### Simplification of Square Roots:
The last part involves simplifying the sum of square roots:
\[
\sqrt{48} + \sqrt{75} + \sqrt{12} + \sqrt{27} + \sqrt{108} + \sqrt{300} + \sqrt{507}
\]
Each of these terms can be simplified by factoring out squares. For example:
\[
\sqrt{48} = \sqrt{16 \times 3} = 4\sqrt{3}
\]
I will proceed to simplify all the square root terms.

Let me start solving them.### Simplification of the square roots:

1. \(\sqrt{48} = 4\sqrt{3} \approx 6.93\)
2. \(\sqrt{75} = 5\sqrt{3} \approx 8.66\)
3. \(\sqrt{12} = 2\sqrt{3} \approx 3.46\)
4. \(\sqrt{27} = 3\sqrt{3} \approx 5.20\)
5. \(\sqrt{108} = 6\sqrt{3} \approx 10.39\)
6. \(\sqrt{300} = 10\sqrt{3} \approx 17.32\)
7. \(\sqrt{507} \approx 22.52\) (This term does not simplify further.)

Adding all these simplified terms together gives:
\[
\text{Total sum} \approx 74.48
\]

### Next Steps
Would you like me to solve the algebraic equations (Problems 1–3), or would you like further clarification on the simplification?

Here are some related questions to consider:

1. How do you simplify algebraic expressions involving both variables and constants?
2. What are the key identities for factoring cubic equations?
3. How can you apply the distributive property to simplify products like \((2x - 3y + 4x)(2x + 3y + 4x)\)?
4. What strategies can be used to simplify sums of square roots?
5. How can you use substitution to solve equations involving multiple variables?

**Tip:** When simplifying square roots, look for perfect square factors within the radicand to make the expression simpler.

Solve the following algebraic problems:
1. Show that: (2x/3y + 3y/2x) results in 4x^2 + 9y^2 + 16x^2 = (2x - 3y + 4x)(2x + 3y + 4x)
2. Given a + 2b = 6, show that a^3 + 27b^3 + 54ab = 216
3. Given a + 2b + 3c = 6, show that a^3 + 8b^3 + 27c^3 = 18abc
Also, simplify the square roots: √48 + √75 + √12 + √27 + √108 + √300 + √507.
