Here are the solutions: 1. \( 7^7 \) \[ 7^7 = 823543 \] 2. \( 5^5 \) \[ 5^5 = 3125 \] 3. \( 4^4 \) \[ 4^4 = 256 \] 4. \( 2^2 \) \[ 2^2 = 4 \] 5. \( 3^3 \) \[ 3^3 = 27 \] 6. \( (-5)^4 \) \[ (-5)^4 = 625 \] 7. \( (-2) \cdot (-2)^6 \) \[ (-2) \cdot (-2)^6 = (-2) \cdot 64 = -128 \] 8. \( (-6)^5 \cdot (-6) \) \[ (-6)^5 \cdot (-6) = (-7776) \cdot (-6) = 46656 \] 9. \( (-0.1)^1 \cdot (-0.1)^1 \) \[ (-0.1)^1 \cdot (-0.1)^1 = (-0.1) \cdot (-0.1) = 0.01 \] 10. \( (-0.2)^1 \cdot (-0.2)^3 \) \[ (-0.2)^1 \cdot (-0.2)^3 = (-0.2) \cdot (-0.008) = 0.0016 \] 11. \( \left( \frac{4}{5} \right)^1 \cdot \left( \frac{4}{5} \right)^1 \) \[ \left( \frac{4}{5} \right)^1 \cdot \left( \frac{4}{5} \right)^1 = \left( \frac{4}{5} \right)^2 = \frac{16}{25} \] 12. \( \left( \frac{1}{2} \right)^1 \cdot \left( \frac{1}{2} \right)^2 \) \[ \left( \frac{1}{2} \right)^1 \cdot \left( \frac{1}{2} \right)^2 = \left( \frac{1}{2} \right)^3 = \frac{1}{8} \] 13. \( A = 3^{19} \left( \frac{1}{9} \right) \) \[ A = 3^{19} \cdot 9^{-1} = 3^{19} \cdot 3^{-2} = 3^{17} \] 14. \( 8 \left( \frac{2}{3} \right)^3 \) \[ 8 \left( \frac{2}{3} \right)^3 = 8 \cdot \frac{8}{27} = \frac{64}{27} \] 15. \( 12^2 \left( \frac{1}{12} \right)^{10} \) \[ 12^2 \left( \frac{1}{12} \right)^{10} = 12^2 \cdot 12^{-10} = 12^{-8} = \frac{1}{12^8} = \frac{1}{429981696} \]
