Answer:
Step-by-step explanation:
(6.8 x 10^-8) + (1.7 x 10^-6)
(0.068 x 10^-6) + (1.7 X 10^-6)
(0.068 + 1.7) x 10^-6
= 1.768 x 10^-6
First you have to convert the (6.8 x 10^-8) to be compatible with 10^-6 so you would move the decimal place 2 places to the right since -8 and -6 are 2 digits apart. Think of it like fractions, to add them they must have the same denominator.
Then once you have converted the 6.8 to 0.068 you can add it to the 1.7.
And now you have your final answer, 1.768 x 10^-6.
