For the second question, the interest rate of 6% yields $24,800.00 while the interest rate of 7% yields$26,398.59.  The question asks how many more dollars the larger yield is than the smaller yield (subtract!).

For the first question:  12²  =  (4·3)2  =  (2·2·3)2  =  (22·3)2  =  24·32

183  =  (2·9)3  =  (2·3·3)3  =  (2·32)3  =  23·36

122·183  =  (24·32)·(23·36)  =  27·38

Since   122·183  = 2x·3y     --->    27·38  =  2x·3y     --->     x = 7   and   y = 8

There are a lot of steps here; any question?
