Question 672581
a*b=2^(2a-b)


3*2=2^(2 x 3-2)


3*2=2^(6-2)


3*2=2^(4)


3*2=16


-------------------------------------------------------


a*b=2^(2a-b)


5*3=2^(2 x 5-3)


5*3=2^(10-3)


5*3=2^(7)


5*3=128


-------------------------------------------------------


(3*2)-(5*3) = (16)-(128)


(3*2)-(5*3) = 16-128


(3*2)-(5*3) = <font color="red">-112</font>
