To add these two numbers, you need to convert them to scientific notation and then add the values.
The first number, 7 * 10^(-8), is already in scientific notation.
The second number, 6 * 10^(-8th power), can be written as 6 * 10^(-8).
Adding the two values:
7 * 10^(-8) + 6 * 10^(-8) = (7 + 6) * 10^(-8) = 13 * 10^(-8)
Therefore, the sum of these two numbers is 13 * 10^(-8).
7 * 10 ^ -8 + 6 * 10 to the negative 8th power
