Answer 1

4 Combining powers and roots ... 25 is read " two raised to the fifth power" or simply "two to the fifth." ... 02, 0. 12, 1. 22, 4. 32, 9. 42, 16. 52, 25. 62, 36. 72, 49. 82, 64. 92, 81. 102, 100.

Answer 2

8^10 =(2^3)^10
4^10 =(2^2)^10
64^2=(2^6)^2
4^9=(2^2)^9
16=2^4
Ans=
$\sqrt{ {2}^{30} + {2}^{20 } } \div \sqrt{ {2}^{12} + ( {2}^{18 } \times {2}^{4} )}$
$\sqrt{ {2}^{20} (1 + {2}^{10} )} \div \sqrt{ {2}^{12} (1 + {2}^{10}) }$
$\sqrt{ {2}^{20} } \div \sqrt{ {2}^{12} }$
$\sqrt{ {2}^{20 - 12} }$
$\sqrt{ {2}^{8} }$
$= 16$
