Question

how do you work out 20000(1+0.07/2)^2*5? i know the answer is 28,211.98 but how do i work it out?

Answer 1

is it ^(2*5) or just ^(2) ?

Answer 2

2*5

Answer 3

2* 10 ^(4) * ( 1 + 0,07/2) ^(10 ) ...you know that you have to calculate 1+ 0,07/2 inside the brackets and just have to power it to 10 and multiply it:
2 * 10^(4) * ( 1 + 0,035)^(10)
2 * 10^(4) * (1,035)^(10)
2 * 10^(4) * 1,41 = 28.211,98 :)

Answer 4

You can type
20000(1+0.07/2)^(2*5)=
into the google search window.

The important thing is you should have (2*5) in parentheses.
Now use order of operations.

Here is a short video on order of operations
