 Question 266383: (1.00-.04)(1+r -.0050^6=1.4185 .96(1+r -.005)^6=1.4185 (1+r -.005)^6=1.4776 I know from class the answer is .0722. However, I can not work the problem beyond this point to solve. I believe I need to divide the exponent by 1/6 on both sides of the equation. But when I do, I do not get the correct answer. My calculator does not have a ^. Even if it does I want to solve the problem by long hand first. Click here to see answer by checkley77(12569)
