Answer:
1. 2^9 = 512
2. 2^3 = 8
3. 7^3 = 343
4. 6^3 = 216
5. 3^6 = 729
Step-by-step explanation:
To start we have to express the number as a multiplication of prime numbers, from there we can take the expression as a power
1. 
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 512
2^9 = 512
2. 
2 x 2 x 2 = 8
2^3 = 8
3. 
7 x 7 x 7 = 343
7^3 = 343
4. 
6 x 6 x 6 = 216
6^3 = 216
5. 
3 x 3 x 3 x 3 x 3 x 3 = 729
3^6 = 729
 
        
             
        
        
        
First simplify the square roots: 

Then simplify the last two terms: 

Since 61 is prime, you can't take a rational root out of it.

Ngl I think it’s 20 because 15 is 5x3 but 60 divided by 3=20 lmk if I’m wrong
