BA II Plus Calculator and Accrual Equiv After Tax Return

Really dumb post but I am having trouble with the keystrokes when calculating the accrual equivalent after tax return, Rae. Given a 150,000 profit and 60,00 base, 9 year horizon how do you input this in your calculator? The formula has the exponent on the outside of the square root which is throwing me off. Thanks

its [(FV/PV)^1/9] - 1 exponent is 0.111…

Initial PV 60,000 FV 150,000 + 60,000 N = 9 CPT I/Y

Thanks, just used the cpt I/Y, seems easiest.

PMT=0, guys
