Answer 2

1. 3x = 1/27; x = (1/27)/3;

x = 1/81.

2. 4x = 16; x = 16/4;

x = 4.

3. 4x = 1/64; x = (1/64)/4;

x = 1/256.

4. 4x = 1/4; x = (1/4)/4;

x = 1/16.

5. 5x = 1/25; x = (1/25)/5

x = 1/125.

6. 5x = 1/625; x = (1/625)/5

x = 1/3125

7. 5x = 125; x = 125/5

x = 25.

8. 6x = 1/36; x = (1/36)/6

x = 1/216.

9. 7x = 1/49; x = (1/49)/7

x = 1/343.

10. 7x = 49; x = 49/7

x = 7.
