I think that the answer you are looking for is 0.3
        
             
        
        
        
Exponents are similar in concept to multipication. Multiplication is repeated addition and exponents are repeated multiplication.
So x^3 = x*x*x
f(-2) = (-2)(-2)(-2) = -8
Try the others For yourself!
        
             
        
        
        
the longer side / the shorter side must be the same for rectangles to be similar.
For  A:  105 / 80  =  1.32
For  B:  120 / 90  =  1.33
For  C:  100 / 75  =  1.47
 
So... only  A  and  B are similar.
