we know that
12²--------> (2²*3)²------> 16*9-----------> 144

20²-18²-----> (2²*5)²-(2*3²)²-----> 16*25-4*81--------> 400-324------> 76

8(4^2)+2^4---------> 2³*(4²)+2²*2²-------> 2³*(2²*2²)+2²*2²----> 128+16----> 144

15²-3^4------> (3*5)²-(3²*3²)------> 9*25-9*9------> 225-81-------> 144

the answers are
8(4^2)+2^4.
