Let's analyze the mathematical expressions visible in the image.

The instructions are in Indonesian and say:

**Latihan 7**
- **Kerjakan soal-soal berikut dengan benar!**
   (Solve the following problems correctly!)

**1. Sederhanakan bentuk-bentuk berikut!**
   (Simplify the following expressions!)

### The problems are:

**a.** \[
\left(a^{\frac{2}{3}}\right)^2 \times a^{\frac{1}{2}}
\]

**b.** \[
\left(\frac{a^{\frac{2}{3}} b^{-3}}{a^{-3} b^{-2}}\right)^{\frac{3}{4}}
\]

Let’s start by simplifying each of these.

### Solution for (a):
Expression: \[
\left(a^{\frac{2}{3}}\right)^2 \times a^{\frac{1}{2}}
\]

1. First, apply the power of a power rule: 
   \[
   \left(a^{\frac{2}{3}}\right)^2 = a^{\frac{4}{3}}
   \]
   
2. Multiply the exponents of \(a\):
   \[
   a^{\frac{4}{3}} \times a^{\frac{1}{2}} = a^{\frac{4}{3} + \frac{1}{2}}
   \]
   
3. Find the common denominator and add the fractions:
   \[
   \frac{4}{3} + \frac{1}{2} = \frac{8}{6} + \frac{3}{6} = \frac{11}{6}
   \]

Final simplified form:
\[
a^{\frac{11}{6}}
\]

### Solution for (b):
Expression: \[
\left(\frac{a^{\frac{2}{3}} b^{-3}}{a^{-3} b^{-2}}\right)^{\frac{3}{4}}
\]

1. Simplify inside the parentheses:
   \[
   \frac{a^{\frac{2}{3}}}{a^{-3}} = a^{\frac{2}{3} - (-3)} = a^{\frac{2}{3} + 3} = a^{\frac{2}{3} + \frac{9}{3}} = a^{\frac{11}{3}}
   \]
   \[
   \frac{b^{-3}}{b^{-2}} = b^{-3 - (-2)} = b^{-3 + 2} = b^{-1}
   \]
   
   Now the expression becomes:
   \[
   \left(a^{\frac{11}{3}} b^{-1}\right)^{\frac{3}{4}}
   \]

2. Apply the exponent to both \(a\) and \(b\):
   \[
   a^{\frac{11}{3} \times \frac{3}{4}} = a^{\frac{11}{4}}, \quad b^{-1 \times \frac{3}{4}} = b^{-\frac{3}{4}}
   \]

Final simplified form:
\[
a^{\frac{11}{4}} b^{-\frac{3}{4}}
\]
