A= ( 3.4 . 2^16) / 11. 2^13 . 4 ^11 - 16 ^ 9
=(3.2^2.2^16)/11.2^13.2^22-2^36
=3.2^18/11.2^35-2^36
=3.2^18/2^35(11-2)
=3.2^18/2^35.3^2
=1/2^17.3
b= ( 3. 42^4) ^2 / 5. 2^5 . 4^2 - 16^2
=(3.42^8)/5.2^5.2^4-2^8
=(3.42^8)/5.2^9-2^8
=(3.42^8)/3^28(5-1)
=(3.42^8)/3^28.4
=(3.42^8)/3^28.2^2
=(3.42^8)/3^8.3^22
=14^8/3^21
