URGENT REAL URGENT: How do I calculate exponents for this question, Using a Scientific Calculator TI-30X IIB?
THe number of mutual funds in Canada, M, is modeled by the equation M =460(1.19)^n, where n is the number of years since 1989.
a) When will the number of mutual funds reach 10,000. Answered I divided 10,000 by the equation 460(1.19), and recieved 21.73.
b) How many years will it take for the number of mutual funds to triple. I need to figure out the exponent for this one.
The calculator I am using is a Texas Instruments TI-30X IIB, and it is just a scientifc calculator.
Thank you to all.

For a, the equation is 10000 = 460 (1.19^n)
Dividing by 460 gives 21.739 = 1.19^n
Now you must take the log of both sides to get the exponent n to be multiplied instead:
log 21.739 = n log 1.19
So divide log 21.739 by log 1.19 to get n
Then for the other, just put whatever 3 times 460 is in for M and do the same thing.

With saying urgency, it's that squooshy sensation of the tongue when you squeeze out the "g" in anticipation of the "nnnnncccccceeee" that gets me every time. I feel pretty lacksydaisy of late too. It's a phase. Waiting for the summer days. Or is it daze? I forget.
