THis quesiton was answered by geno before, but i was not sure what to combine. Sorry geno!
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?
