<br>
The example you show makes no sense; so I will ignore it....<br>
For question a:  5^2 = 25; 5^3 = 125; 5^4 = 625; 5^5 = 3125; 5^6 = 15625; ....<br>
For question b: 10^2 = 100; 10^3 = 1000; 10^4 = 10000; 10^5 = 100000; 10^6 = 1000000....<br>
For question c:  2^8 = 256; 2^9 = 512; 2^10 = 1024; 2^11 = 2048; 2^12 = 4096; ....<br>
