Let p=10000, r=0.1, n=1, and t=2 and plug them into A=10000%281%2B0.1%2F1%29%5E%281%2A2%29

A=10000%281%2B0.1%2F1%29%5E%281%2A2%29 Start with the given expression
A=10000%281%2B0.1%29%5E%281%2A2%29 Divide 0.1 by 1 to get 0.1
A=10000%281%2B0.1%29%5E%282%29 Multiply the exponents 1 and 2 to get 2
A=10000%281.1%29%5E%282%29 Add 1 and 0.1 to get 1.1
A=10000%281.21%29 Raise 1.1 to 2 to get 1.21
A=12100 Multiply 10000 and 1.21 to get 12100

So the return is $12100
