Need help desperately

a.   4cd²       b.  3a²b³

Step-by-step explanation:

 =      

  =        Reduce number.  Substract exponent largest power

                           smallest power  

   =   4cd²  

b.    

              Reduce number.  Substract exponent largest power

                              smallest power  

    = 3a²b³

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the answer is simply just 6n add the two together as they have an n
