10 + (10*10) to the negative³

10 + (10x10) ^-3

10 + 10^-3 • 10^-3

10 + 10^-3 + - 3

10 + 10^-6

10 + 1/10^6

10/1 = 10^1 • 10^6/10^6

10^1+6/10^6 + 1/10^6

10^7/10^6 + 1/10^6

10^7 + 1/10^6

The final solution is 10^7 + 1 / 10^6. You can simply it further by adding the value of 10^7 to 1 and then dividing it by 10^6, to obtain a decimal number.
