The simplest answer, in terms of powers of 2, is 

                                             1
                                      ---------------
                                             16
                                           2
                             4                                     16
Please note that 2     equals 16, and that 2       thus equals 16^4.

Thus, another form in which the answer can be expressed is 

          1                  1
------------- , or ----------- .    If you want to take this further, calculate
        4                      2

Luden [163]

Answer:

You need to invest at a continuous compound interest rate of 6.701355026%

Step-by-step explanation:

The formula to use is the compound interest formula:A=P(1+r/100)^t

where A=Total amount at the end of the investment period

P=Principal amount

R=Rate of interest

T=Investment tenor/time

Now,

350,000=50000(1+r/100)^30 is what needs to be simplified to 6.701355026%
