Let's solve the problems in the image step by step.

### 1. Ubahlah bentuk berikut dalam bentuk pangkat positif (Convert the following into positive exponents):
   \[
   \text{a. } 5^{-3} 
   \]
   To convert a negative exponent to a positive exponent:
   \[
   5^{-3} = \frac{1}{5^3}
   \]
   \[
   \text{Answer: } \frac{1}{5^3}
   \]

   \[
   \text{b. } (-7)^{-4}
   \]
   Similarly:
   \[
   (-7)^{-4} = \frac{1}{(-7)^4}
   \]
   \[
   \text{Answer: } \frac{1}{(-7)^4}
   \]

   \[
   \text{c. } \frac{1}{9^{-4}}
   \]
   Here, to convert:
   \[
   \frac{1}{9^{-4}} = 9^4
   \]
   \[
   \text{Answer: } 9^4
   \]

   \[
   \text{d. } \frac{1}{(-8)^{-3}}
   \]
   Similarly:
   \[
   \frac{1}{(-8)^{-3}} = (-8)^3
   \]
   \[
   \text{Answer: } (-8)^3
   \]

### 2. Ubahlah bentuk berikut dalam bentuk pangkat negatif (Convert the following into negative exponents):
   \[
   \text{a. } 7^6
   \]
   To convert a positive exponent to a negative exponent:
   \[
   7^6 = \frac{1}{7^{-6}}
   \]
   \[
   \text{Answer: } \frac{1}{7^{-6}}
   \]

   \[
   \text{b. } (-9)^8
   \]
   Similarly:
   \[
   (-9)^8 = \frac{1}{(-9)^{-8}}
   \]
   \[
   \text{Answer: } \frac{1}{(-9)^{-8}}
   \]

   \[
   \text{c. } \frac{1}{5^7}
   \]
   To convert the fraction:
   \[
   \frac{1}{5^7} = 5^{-7}
   \]
   \[
   \text{Answer: } 5^{-7}
   \]

   \[
   \text{d. } \frac{1}{2^4}
   \]
   Similarly:
   \[
   \frac{1}{2^4} = 2^{-4}
   \]
   \[
   \text{Answer: } 2^{-4}
   \]
