To simplify with exponent, here are the steps
1. Perform any operation(s) within grouping symbols
2. Simplify any exponent
3. Multiply and divide in order from left to right
4. Add and Subtract in order from left to right

since there are no grouping in the problem our first step is:

1. Simplify the exponent first. 10^3 means multiply 10 x 10 x 10 and 10^ means 10 x 10.

+125.7%2A10%5E3+%2B+75.25%2A10%5E2+

125.7%2A1000+%2B+75.25%2A100


2. Multiply in order from left to right
125,700 + 7525


3. Add in order from left to right
