I would follow the order of operations. Take 1.0105 raise it to the 11th power and then multiply that answer by 294.4.

1.0105^11=1.1217588288...

1.1217588288... * 294.4 = 330.2457992233...

Same with the other equation

294.4(1.0105)^11 , and 106.5(1.0143)^11?
Use a calculator getting 330.25 and 124.5031

If no calculator, use google.

Otherwise you would need to get a table of logarithms.

you would work out the exponents first.
remember the order of operations:
P... parenthesis
E... exponents
M... multiply
D... divide
A... addition
S... subtraction.

after you raise both 1.0105 and 1.0143 to the 11th power, multiply your answers to 294.4 and 106.5, respectively.

The easy way: you need a scientific calculator.
The hard way: (or in case you can't raise decimal powers with your calculator), use logarithms and exp functions: for example: 294.4(1.0105)^11 = 294.4 * exp ( ln [ (1.0105)^11]))
(since exp and ln are inverse functions)
Then using exponents laws:
294.4 * exp ( ln [ (1.0105)^11])) = 294.4 * exp (11* ln [ (1.0105)))
But again you need a scientific calculator for getting the final value!

You can drop 294.4*(1.0105)^11 into Google, or you can take 294.4 times 1.0105 eleven times.
